Version 5.6.1 ------------- Released March 18, 2025 Fixes +++++ - (:issue:`1077`) Fix runtime modification of a config string (TWO_FACTOR_METHODS) - (:issue:`1078`) Fix CLI user_create when model doesn't contain username - (:issue:`1076`) xxx_util_cls instances should be public and documented. Backwards Compatibility Concerns +++++++++++++++++++++++++++++++++ As part of :issue:`1076` the following cleanup was done: - The xxx_util_cls arguments are now stored in 'private' instance variables - they are never used after Flask-Security initialization and have never been documented. - The xxx_util_cls options should only be set as part of Flask-Security construction. Setting them via init_app(kwargs) or app.config["SECURITY_XX"] has been deprecated. Version 5.6.0 ------------- Released February 12, 2025 Features & Improvements +++++++++++++++++++++++ - (:issue:`1038`) Add support for 'secret_key' rotation (jamesejr) - (:issue:`980`) Add support for username recovery in simple login flows (jamesejr) - (:issue:`1055`) Add support for changing username - (:pr:`1048`) Add support for Python 3.13 - (:issue:`1043`) Unify Register forms (and split out re-type password option) Please read :ref:`register_form_migration`. Fixes +++++ - (:pr:`1062`) Fix duplicate HTML ids in templates. - (:pr:`1067`) Fix more duplicate HTML ids in templates. - (:issue:`1064`) Ensure templates pass W3C validation (see below) Docs and Chores +++++++++++++++ - (:pr:`1052`) Remove deprecated TWO_FACTOR configuration variables - (:pr:`1069`) Update ES and IT translations (gissimo) - (:pr:`1071`) Improve templates - two-factor is hyphenated, re-authenticate is not. Also try to embed links into xlatable strings. Notes +++++ Python 3.13 removed ``crypt``, which passlib attempts to import and use as part of its safe_crypt() method (fallback is to return None). However - that method only appears to be called in a few crypt handlers and for bcrypt - only for the built-in bcrypt - not if the bcrypt package is installed. passlib is not maintained - a new fork (10/1/2024) (https://pypi.org/project/libpass/) seems promising and has been tested with python 3.13 and Flask-Security. If that fork matures we will change the dependencies appropriately. The register forms have been combined - or more accurately - there is a new RegisterFormV2 that subsumes the features of both the old RegisterForm and ConfirmRegisterForm. Please read :ref:`register_form_migration`. The SECURITY_TWO_FACTOR_{SECRET, URI_SERVICE_NAME, SMS_SERVICE, SMS_SERVICE_CONFIG} have been removed (they have been deprecated for a while). Use the equivalent :py:data:`SECURITY_TOTP_SECRETS`, :py:data:`SECURITY_TOTP_ISSUER`, :py:data:`SECURITY_SMS_SERVICE` and :py:data:`SECURITY_SMS_SERVICE_CONFIG`. Backwards Compatibility Concerns +++++++++++++++++++++++++++++++++ The fixes to all the templates to pass W3C validation could introduce some incompatibilities: - All templates now have a default - before, the <title> element was empty. - The HTML id of the rescue form submit button was changed to 'rescue' - The HTML id of the webauthn delete form name field was changed to 'delete-name' - Some template headings were changed to improve consistency - The csrf_token HTML id was changed on us_setup.html, wan_register.html, two_factor_setup.html two_factor_verify_code.html, us_verify.html, verify.html for the second form on the page. - On us_setup.html and two_factor_setup.html the submit code button HTML id was changed. Version 5.5.2 ------------- Released August 5, 2024 More attempts to upload to pypi both flask-security and flask-security-too. No code changes - however the build manifest changed so the source distribution contents might be slightly different. Docs and Chores +++++++++++++++ - (:pr:`1019`) Separate publish workflows for each pypi package Version 5.5.1 ------------- Released August 1, 2024 I am pleased to announce that Flask-Security-Too is now part of pallets-eco and has returned to be released as 'Flask-Security'. For the foreseeable future, we will publish the same release to both Flask-Security and Flask-Security-Too on PyPI. There are no code changes. Docs and Chores +++++++++++++++ - (:pr:`1015`) Convert docs, links, badges, etc to pallets-eco Version 5.5.0 ------------- Released July 24, 2024 Features & Improvements +++++++++++++++++++++++ - (:issue:`956`) Add support for changing registered user's email (:py:data:`SECURITY_CHANGE_EMAIL`). - (:issue:`944`) Change default password hash to argon2 (was bcrypt). See below for details. - (:pr:`990`) Add freshness capability to auth tokens (enables /us-setup to function w/ just auth tokens). - (:pr:`991`) Add support to /tf-setup to not require sessions (use a state token). - (:issue:`994`) Add support for Flask-SQLAlchemy-Lite - including new all-inclusive models that conform to sqlalchemy latest best-practice (type-annotated). - (:pr:`1007`) Convert other sqlalchemy-based datastores from legacy 'model.query' to best-practice 'select' - (:issue:`983`) Allow applications more flexibility defining allowable redirects. Fixes +++++ - (:pr:`972`) Set :py:data:`SECURITY_CSRF_COOKIE` at beginning (GET /login) of authentication ritual - just as we return the CSRF token. (thanks @e-goto) - (:issue:`973`) login and unified sign in should handle GET for authenticated user consistently. - (:pr:`995`) Don't show sms options if not defined in US_ENABLED_METHODS. (fredipevcin) - (:pr:`1009`) Change :py:data:`SECURITY_DEPRECATED_HASHING_SCHEMES` to ``["auto"]``. Docs and Chores +++++++++++++++ - (:pr:`979`) Update Russian translations (ademaro) - (:pr:`1004`) Update ES and IT translations (gissimo) - (:pr:`981` and :pr:`977`) Improve docs - (:pr:`992`) The long deprecated `get_token_status` is no longer exported - (:pr:`992`) Drop Python 3.8 support. - (:issue:`1001`) Try a different approach to typing User and Role models. Backwards Compatibility Concerns +++++++++++++++++++++++++++++++++ - Notes around the change to argon2 as the default password hash: - applications should add the argon2_cffi package to their requirements (it is included in the flask_security[common] extras). - leave bcrypt installed so that old passwords still work. - the default configuration will re-hash passwords with argon2 upon first use. - Changes to /tf-setup The old path - using state set in the session still works as before. The new path is just for the case an authenticated user wants to change their 2FA setup. - Changes to sqlalchemy-based datastores Flask-Security no longer uses the legacy model.query - all DB access is done via `select(xx).where(xx)`. As a result the find_user() method now only takes a SINGLE column:value from its kwargs - in prior releases all kwargs were passed into the query.filter. Version 5.4.3 ------------- Released March 23, 2024 Fixes +++++ - (:issue:`950`) Regression - some templates no longer getting correct config (thanks pete7863). - (:issue:`954`) CSRF not properly ignored for application forms using :py:data:`SECURITY_CSRF_PROTECT_MECHANISMS`. - (:pr:`957`) Improve jp translations (e-goto) - (:issue:`959`) Regression - datetime_factory should still be an attribute (thanks TimotheeJeannin) - (:issue:`942`) :py:data:`SECURITY_RETURN_GENERIC_RESPONSES` hid email validation/syntax errors. Version 5.4.2 ------------- Released March 8, 2024 Fixes +++++ - (:issue:`946`) OpenAPI spec missing. - (:pr:`945`) Doc fixes (e-goto) - (:pr:`941`) Update ES/IT translations (gissimo) Version 5.4.0 & 5.4.1 ---------------------- Released February 26, 2024 Among other changes, this continues the process of dis-entangling Flask-Security from Flask-Login and may require some application changes due to backwards incompatible changes. Features & Improvements +++++++++++++++++++++++ - (:issue:`879`) Work with Flask[async]. view decorators and signals support async handlers. - (:pr:`900`) CI support for python 3.12 - (:pr:`901`) Work with py_webauthn 2.0 (and only 2.0+) - (:pr:`899`) Improve (and simplify) Two-Factor setup. See below for backwards compatability issues and new functionality. - (:issue:`912`) Improve oauth debugging support. Handle next propagation in a more general way. - (:pr:`877`) Make AnonymousUser (Flask-Login) optional and deprecated. - (:pr:`906`) Remove undocumented and untested looking in session for possible 'next' redirect location. - (:pr:`881`) No longer rely on Flask-Login.unauthorized callback. See below for implications. - (:issue:`904`) Changes to default unauthorized handler - remove use of referrer header (see below) and document precise behavior. - (:pr:`927`) The authentication_token format has changed - adding per-token expiry time and future session ID. Old tokens are still accepted. Docs and Chores +++++++++++++++ - (:pr:`889`) Improve method translations for unified signin and two factor. Remove support for Flask-Babelex. - (:pr:`911`) Chore - stop setting all config as attributes. init_app(\*\*kwargs) can only set forms, flags, and utility classes (see below for compatibility concerns). - (:pr:`873`) Update Spanish and Italian translations. (gissimo) - (:pr:`855`) Improve translations for two-factor method selection. (gissimo) - (:pr:`866`) Improve German translations. (sr-verde) - (:pr:`911`) Remove deprecation of AUTO_LOGIN_AFTER_CONFIRM - it has a reasonable use case. - (:pr:`931`) Update message extraction - note that the CONFIRM_REGISTRATION message was changed to improve readability. Fixes +++++ - (:issue:`845`) us-signin magic link should use fs_uniquifier (not email). - (:issue:`893`) Improve open-redirect vulnerability mitigation. (see below) - (:issue:`875`) user_datastore.create_user has side effects on mutable inputs. (NoRePercussions) - (:pr:`878`) The long deprecated _unauthorized_callback/handler has been removed. - (:issue:`884`) Oauth re-used POST_LOGIN_VIEW which caused confusion. See below for the new configuration and implications. - (:pr:`908`) Improve CSRF documentation and testing. Fix bug where a CSRF failure could return an HTML page even if the request was JSON. - (:issue:`925`) Register with JSON and authentication token failed CSRF. (lilz-egoto) - (:issue:`870`) Fix 2 issues with CSRF configuration. - (:pr:`914`) It was possible that if :data:`SECURITY_EMAIL_VALIDATOR_ARGS` were set that deliverability would be checked even for login. Backwards Compatibility Concerns +++++++++++++++++++++++++++++++++ - Passing in an AnonymousUser class as part of Security initialization has been removed. - The never-public method _get_unauthorized_response has been removed. - Social-Oauth - a new configuration variable :py:data:`SECURITY_POST_OAUTH_LOGIN_VIEW` was introduced and it replaces :py:data:`SECURITY_POST_LOGIN_VIEW` in the oauthresponse logic when :py:data:`SECURITY_REDIRECT_BEHAVIOR` == `"spa"`. - Two-Factor setup. Prior to this release when setting up "SMS" the `/tf-setup` endpoint could be POSTed to w/o a phone number, and then another POST could be made to set the phone number. This has always been confusing and added complexity to the code. Now, if "SMS" is selected, the phone number must be supplied (which has always been supported). Other changes: - The default two-factor-setup.html template now has a more generic `"Enter code to complete setup"` message. - Make sure the `"disable"` option first. - Adding any currently configured two-factor method on setup failure. - The two_factor_verify template won't show the rescue form if it isn't set. - A GET on /tf-validate now returns the two-factor-validate-form always - before if the client was validating a new method, it would return the two-factor-setup-form - After successfully disabling two-factor the client is redirected to :py:data:`SECURITY_TWO_FACTOR_POST_SETUP_VIEW` rather than :py:data:`SECURITY_POST_LOGIN_VIEW`. - Bring unauthenticated handling completely into Flask-Security: Prior to this release, Flask-Security's :meth:`.Security.unauthn_handler` - called when a request wasn't properly authenticated - handled JSON requests then delegated form responses to Flask-Login's unauthenticated_callback. That logic has been moved into Flask-Security and Flask-Login is configured to call back into Flask-Security's handler. While the logic is very similar the following differences might be observed: - Flask-Login's FORCE_HOST_FOR_REDIRECTS configuration isn't honored - Flask-Login's USE_SESSION_FOR_NEXT configuration isn't honored - The flashed message is SECURITY_MSG_UNAUTHENTICATED rather than SECURITY_MSG_LOGIN. Furthermore, SECURITY_MSG_UNAUTHENTICATED was reworded to read better. - Flask-Login uses `urlencode` to encode the `next` query param - which quotes the '/' character. Werkzeug (which Flask-Security uses to build the URL) uses `quote` which considers '/' a safe character and isn't encoded. - The signal sent on an unauthenticated request has changed to :data:`user_unauthenticated`. Flask-Login used to send a `user_unauthorized` signal. - Flask-Security no longer configures anything related to Flask-Login's `fresh_login` logic. This shouldn't be used - instead use Flask-Security's :meth:`flask_security.auth_required` decorator. - Support for Flask-Babelex has been removed. Please convert to Flask-Babel. - JSON error response has changed due to issue with WTForms form-level errors. When WTForms introduced form-level errors they added it to the form.errors response using `None` as a key. When serializing it, it would turn into "null". However, if there is more than one error the default settings for JSON serialization in Flask attempt to sort the keys - which fails with the `None` key. An issue has been filed with WTForms - and maybe it will be changed. Flask-Security now changes any `None` key to `""`. - The default unauthorized handler behavior has changed slightly and is now documented. The default (:data:`SECURITY_UNAUTHORIZED_VIEW` == ``None``) has not changed (a default HTTP 403 response). The precise behavior when :data:`SECURITY_UNAUTHORIZED_VIEW` is set was never documented. The important change is that Flask-Security no longer ever looks at the request.referrer header and will never redirect to it. If an application needs that, it can provide a callable that can return that or any other header. - Configuration variables (and other things) are no longer added as attributes on the Security instance. For example `security.username_enable` no longer exists - this could be an issue in code or templates. For templates, Flask places `config` in the Jinja context - so rather than using an attribute, use `config["SECURITY_USERNAME_ENABLE"]` for the example above. - Open Redirect mitigation. Release 4.1.0 had a fix for :issue:`486` involving a potential open redirect. This was very low priority since the default configuration of Werkzeug (always convert the Location header to absolute URL) rendered the vulnerability un-exploitable. The solution at that time was to add an optional regex looking for these bizarre URLs that from a HTTP spec perspective are relative, but various browsers would interpret as absolute. In Werkzeug release 2.1 the default was changed so that the Location header was allowed to be a relative URL. This made the open redirect vulnerability much more likely to be exploitable. More recently, additional bizarre URLs were found, as documented in :issue:`893`. More work was done and a patch release 5.3.3 was published. This fix utilized changing the Werkzeug default back to absolute and an updated regex. Comments and thoughts by @gmanfuncky proposed a much better solution and that is in 5.4. This implementation is independent of Werkzeug (and relative Location headers are again the default). The entire regex option has been removed. Instead, any user-supplied path used as a redirect is parsed and quoted. Notes ++++++ - Historically, the **current_user** proxy (managed by Flask-Login) always pointed to a user object. If the user wasn't authenticated, it pointed to an AnonymousUser object. With this release, setting :py:data:`SECURITY_ANONYMOUS_USER_DISABLED` to `True` will force **current_user** to be set to `None` if the requesting user isn't authenticated. It should be noted that this is in support of a proposal by the Pallets team to remove AnonymousUser from Flask-Login - as well as deprecating the `is_authenticated` property. The default behavior (`False`) should be the same as prior releases. A new function `_fs_is_user_authenticated` is now part of the render_template context that templates can use instead of `current_user.is_authenticated`. Version 5.3.3 ------------- Released December 29, 2023 Fixes +++++ - (:issue:`893`) Once again work on open-redirect vulnerability - this time due to newer Werkzeug. Addresses: CVE-2023-49438 Version 5.3.2 ------------- Released October 23, 2023 Fixes ++++++ - (:issue:`859`) Update Quickstart to show how to properly handle SQLAlchemy connections. - (:issue:`861`) Auth Token not returned from /tf-validate. (thanks lilz-egoto) - (:pr:`864`) Fix for latest email_validator deprecation - bump minimum to 2.0.0 - (:pr:`865`) Deprecate passing in the anonymous_user class (sent to Flask-Login). Version 5.3.1 ------------- Released October 14, 2023 **Please Note:** - If your application uses webauthn you must use pydantic < 2.0 until the issue with user_handle is resolved. Fixes ++++++ - (:issue:`847`) Compatability with Flask 3.0 (wangsha) - (:issue:`829`) Revert change in 5.3.0 that added a Referrer-Policy header. - (:issue:`826`) Fix error in quickstart (codycollier) - (:pr:`835`) Update Armenian translations (amkrtchyan-tmp) - (:pr:`831`) Update German translations. (sr-verde) - (:issue:`853`) Fix 'next' propagation when passed as form.next (thanks cariaso) Version 5.3.0 ------------- Released July 27, 2023 This is a minor version bump due to some small backwards incompatible changes to WebAuthn, recoverability (/reset), confirmation (/confirm) and the two factor validity feature. Fixes ++++++ - (:pr:`807`) Webauthn Updates to handling of transport. - (:pr:`809`) Fix MongoDB support by eliminating dependency on flask-mongoengine. Improve MongoDB quickstart. - (:issue:`801`) Fix Quickstart for SQLAlchemy with scoped session. - (:issue:`806`) Login no longer, by default, checks for email deliverability. - (:issue:`791`) Token authentication is no longer accepted on endpoints which only allow 'session' as authentication-method. (N247S) - (:issue:`814`) /reset and /confirm and GENERIC_RESPONSES and additional form args don't mix. - (:issue:`281`) Reset password can be exploited and other OWASP improvements. - (:pr:`817`) Confirmation can be exploited and other OWASP improvements. - (:pr:`819`) Convert to pyproject.toml, build, remove setup.py/.cfg. - (:pr:`823`) the tf_validity feature now ONLY sets a cookie - and the token is no longer returned as part of a JSON response. - (:pr:`825`) Fix login/unified signin templates to properly send CSRF token. Add more tests. - (:pr:`826`) Improve Social Oauth example code. Backwards Compatibility Concerns +++++++++++++++++++++++++++++++++ - To align with the W3C WebAuthn Level2 and 3 spec - transports are now part of the registration response. This has been changed BOTH in the server code (using webauthn data structures) as well as the sample javascript code. If an application has their own javascript front end code - it might need to be changed. - The tf_validity feature :py:data:`SECURITY_TWO_FACTOR_ALWAYS_VALIDATE` used to set a cookie if the request was form based, and return the token as part of a JSON response. Now, this feature is ONLY cookie based and the token is no longer returned as part of any response. - Reset password was changed to adhere to OWASP recommendations and reduce possible exploitation: - A new email (with new token) is no longer sent upon expired token. Users must restart the reset password process. - The user is no longer automatically logged in upon successful password reset. For backwards compatibility :py:data:`SECURITY_AUTO_LOGIN_AFTER_RESET` can be set to ``True``. Note that this compatibility feature is deprecated and will be removed in a future release. - Identity information (identity, email) is no longer sent as part of the URL redirect query params. - The SECURITY_MSG_PASSWORD_RESET_EXPIRED message no longer contains the user's identity/email. - The default for :py:data:`SECURITY_RESET_PASSWORD_WITHIN` has been changed from `5 days` to `1 days`. - The response to GET /reset/<token> sets the HTTP header `Referrer-Policy` to `no-referrer` as suggested by OWASP. *PLEASE NOTE: this was backed out in 5.3.1* - Confirm email was changed to adhere to OWASP recommendations and reduce possible exploitation: - A new email (with new token) is no longer sent upon expired token. Users must restart the confirmation process. - Identity information (identity, email) is no longer sent as part of the URL redirect query params. - The :py:data:`SECURITY_AUTO_LOGIN_AFTER_CONFIRM` configuration variable now defaults to ``False`` - meaning after a successful email confirmation, the user must still sign in using the usual mechanisms. This is to align better with OWASP best practices. Setting it to ``True`` will restore prior behavior. - The SECURITY_MSG_CONFIRMATION_EXPIRED message no longer contains the user's identity/email. - The response to GET /reset/<token> sets the HTTP header `Referrer-Policy` to `no-referrer` as suggested by OWASP. *PLEASE NOTE: this was backed out in 5.3.1* Version 5.2.0 ------------- Released May 6, 2023 Note: Due to rapid deprecation and removal of APIs from the Pallets team, maintaining the testing of back versions of various packages is taking too much time and effort. In this release only current versions of the various dependent packages are being tested. Fixes +++++ - (:issue:`764`) Remove old Werkzeug compatibility check. - (:issue:`777`) Compatibility with Quart. - (:pr:`780`) Remove dependence on pkg_resources / setuptools (use importlib_resources package) - (:pr:`792`) Fix tests to work with latest Werkzeug/Flask. Update requirements_low to match current releases. - (:pr:`792`) Drop support for Python 3.7 Known Issues ++++++++++++ - Flask-mongoengine hasn't released in a while and currently will not work with latest Flask and Flask-Security-Too/Flask-Security (this is due to the JSONEncoder being deprecated and removed). Backwards Compatibility Concerns +++++++++++++++++++++++++++++++++ - The removal of pkg_resources required changing the config variable :py:data:`SECURITY_I18N_DIRNAME`. If your application modified or extended this configuration variable, a small change will be required. Version 5.1.2 ------------- Released March 12, 2023 Fixes +++++ - (:issue:`771`) Hungarian translations not working. - (:pr:`769`) Fix documentation for send_mail. (gg) - (:pr:`768`) Fix for latest mongoengine and mongomock. - (:pr:`766`) Fix inappropriate use of &thinsp& in French translations.

Version 5.1.1 ------------- Released March 1, 2023 Fixes +++++ - (:issue:`740`) Fix 2 Flask apps in same thread with USERNAME_ENABLE set. There was a too aggressive config check. - (:pr:`739`) Update Russian translations. (ademaro) - (:pr:`743`) Run all templates through a linter. (ademaro) - (:pr:`757`) Fix json/flask backwards compatibility hack. - (:issue:`759`) Fix quickstarts - make sure they run using `flask run` - (:pr:`755`) Fix unified signup when two-factor not enabled. (sebdroid) - (:pr:`763`) Add dependency on setuptools (pkg_resources). (hroncok) Version 5.1.0 ------------- Released January 23, 2023 Features ++++++++ - (:issue:`667`) Expose form instantiation. See :ref:`form_instantiation`. - (:issue:`693`) Option to encrypt recovery codes. - (:pr:`716`) Support for authentication via 'social' oauth. - (:pr:`721`) Support for Python 3.11 Fixes +++++ - (:pr:`678`) Fixes for Flask-SQLAlchemy 3.0.0. (jrast) - (:pr:`680`) Fixes for sqlalchemy 2.0.0 (jrast) - (:issue:`697`) Webauthn and Unified signin features now properly take into account blueprint prefixes. - (:issue:`699`) Properly propagate `?next=/xx` - the verify, webauthn, and unified signin endpoints, that had multiple redirects, needed fixes. - (:pr:`696`) Add Hungarian translations. (xQwexx) - (:issue:`701`) Two factor redirects ignored url_prefix. Added a :py:data:`SECURITY_TWO_FACTOR_ERROR_VIEW` configuration option. - (:issue:`704`) Add configurations for static folder/URL and make sure templates reference blueprint relative static folder. - (:issue:`709`) Make (some) templates look better by using single quotes instead of double quotes. - (:issue:`690`) Send entire context to MailUtil::send_mail (patrickyan) - (:pr:`728`) Support for Flask-Babel 3.0.0 - (:issue:`692`) Add configuration option :py:data:`SECURITY_TWO_FACTOR_POST_SETUP_VIEW` which is redirected to upon successful change of a two factor method. - (:pr:`733`) The ability to pass in a LoginManager instance which was deprecated in 5.0 has been removed. - (:issue:`732`) If :py:data:`SECURITY_USERNAME_REQUIRED` was ``True`` then users couldn't login with just an email. - (:issue:`734`) If :py:data:`SECURITY_USERNAME_ENABLE` is set, bleach is a requirement. - (:pr:`736`) The unauthz_handler now takes a function name, not the function! Backwards Compatibility Concerns +++++++++++++++++++++++++++++++++ - Each form class used to be set as an attribute on the Security object. With the new form instantiation model, they no longer are. - After a successful update/change of a two-factor method, the user was redirected to :py:data:`SECURITY_POST_LOGIN_VIEW`. Now it redirects to :py:data:`SECURITY_TWO_FACTOR_POST_SETUP_VIEW` which defaults to `".two_factor_setup"`. - The :meth:`.Security.unauthz_handler` now takes a function name - not the function - which never made sense. Version 5.0.2 ------------- Released September 23, 2022 Fixes +++++ - (:issue:`673`) Role permissions backwards compatibility bug. For SQL based datastores that use Flask-Security's models.fsqla_vx - there should be NO issues. If you declare your own models - please see the 5.0.0 releases notes for required change. Version 5.0.1 ------------- Released September 6, 2022 Fixes +++++ - (:pr:`662`) Fix Change Password regression. (tysonholub) Version 5.0.0 ------------- Released August 27, 2022 **PLEASE READ CHANGE NOTES CAREFULLY - THERE ARE LIKELY REQUIRED CHANGES YOU WILL HAVE TO MAKE.** Features ++++++++ - (:issue:`475`) Support for WebAuthn. - (:issue:`479`) Support Two-factor recovery codes. - (:issue:`585`) Provide option to prevent user enumeration (i.e. Generic Responses). - (:pr:`532`) Support for Python 3.10. - (:pr:`657`, :pr:`655`) Support for Flask >= 2.2. - (:pr:`540`) Improve Templates in support of JS required by WebAuthn. - (:pr:`608`) Add Icelandic translations. (ofurkusi) - (:pr:`650`) Update German translations. (sr-verde) - (:issue:`256`) Add custom HTML attributes to improve user experience. This changed LoginForm quite a bit - please see backwards compatability concerns below. The default LoginForm and template should be the same as before. - (:pr:`638`) The JSON errors response has been unified. Please see backwards compatibility concerns below. - Updated all-inclusive data models (fsqla_v3). Add fields necessary for the new WebAuthn and Two-Factor recovery codes features. Changed `us_phone_number` to be unique (but not required). Changed `password` to be nullable. Deprecations ++++++++++++ - (:pr:`568`) Deprecate the old passwordless feature in favor of Unified Signin. - (:pr:`568`) Deprecate replacing login_manager so we can possibly vendor that in in the future. - (:pr:`654`) The previously deprecated methods RoleMixin.add_permissions and RoleMixin.remove_permissions have been removed. - (:pr:`657`) The ability to pass in a json_encoder_cls as part of initialization has been removed since Flask 2.2 has deprecated and replaced that functionality. - (:pr:`655`) Flask has deprecated @before_first_request. This was used mostly in examples/quickstart. These have been changed to use app.app_context() prior to running the app. Flask-Security itself used it in 2 places - to populate `_` in jinja globals if Babel wasn't initialized and to perform various configuration sanity checks w.r.t. WTF CSRF. All Flask-Security templates have been converted to use `_fsdomain` rather than ``_`` so Flask-Security no longer sets ``_`` into jinja2 globals. The configuration checks have been moved to the end of Security::init_app() - so it is now imperative that `FlaskWTF::CSRFProtect()` be called PRIOR to initializing Flask-Security. - encrypt_password method has been removed. It has been deprecated since 2.0.2 - get_token_status has been deprecated. Fixes +++++ - (:pr:`591`) Make the required zxcvbn complexity score configurable. (mephi42) - (:issue:`531`) Get rid of Flask-Mail. Flask-Mailman is now the default preferred email package. Flask-Mail is still supported so there should be no backwards compatability issues. - (:issue:`597`) A delete option has been added to us-setup (form and view). - (:pr:`625`) Improve username support - the LoginForm now has a separate field for username if ``SECURITY_USERNAME_ENABLE`` is True, and properly displays input fields only if the associated field is an identity attribute (as specified by :py:data:`SECURITY_USER_IDENTITY_ATTRIBUTES`). - (:pr:`627`) Improve empty password handling. Prior, an unguessable password was set into the user record when a user registered without a password - now, the DB user model has been changed to allow nullable passwords. This provides a better user experience since Flask-Security now knows if a user has an empty password or not. Since registering without a password is not a mainstream feature, a new configuration variable :py:data:`SECURITY_PASSWORD_REQUIRED` has been added (defaults to ``True``). - (:issue:`479`) A new configuration option :py:data:`SECURITY_TWO_FACTOR_RESCUE_EMAIL` has been added that allows disabling that feature - defaults to backwards compatible ``True`` - (:issue:`658`) us_phone_number needs to be validated to be unique. Backward Compatibility Concerns ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ For unified signin: - The redirect after a successful us-setup used to redirect to ``SECURITY_US_POST_SETUP_VIEW`` or ``SECURITY_POST_LOGIN_VIEW`` (which would default to '/'). Now it just redirects to ``SECURITY_US_POST_SETUP_VIEW`` which defaults back to the ``/us-setup`` view. - The ability to authenticate using a one-time email link was automatically setup by the system for all users. "email" now behaves like the other unified sign in methods and must be explicitly set up - with the exception that if a user registers WITHOUT a password, the system will setup the one-time email link option - since otherwise the user would never be able to authenticate. - ``/us-signin/send-code`` didn't used to check if the user account required confirmation it just sent a code and the ``/us-signin`` endpoint did the confirmation check. Now ``send-code`` does the confirmation check and won't send a code unless the user is confirmed. - In ``us-verify`` the 'code_methods' item now lists just active/setup methods that generate a code not ALL possible methods that generate a code. - ``SECURITY_US_VERIFY_SEND_CODE_URL`` and ``SECURITY_US_SIGNIN_SEND_CODE_URL`` endpoints are now POST only. - Empty passwords were always permitted when ``SECURITY_UNIFIED_SIGNIN`` was enabled - now an additional configuration variable ``SECURITY_PASSWORD_REQUIRED`` must be set to False. - ``SECURITY_US_VERIFY_SEND_CODE_URL`` and ``SECURITY_US_SIGNIN_SEND_CODE_URL`` used to send ``code_sent`` to the template. Now they flash the ``SECURITY_MSG_CODE_HAS_BEEN_SENT`` message. - With the addition of being able to delete a previously setup up sign in method, the signal `us_profile_changed` arguments have changed. `method` is now `methods` and is a list, and a new argument `delete` is True if a sign in option was deleted. Login: - Since the beginning of time, the flask-security login form has accepted any input in the 'email' field, and used that to check if it corresponds to any field in ``SECURITY_USER_IDENTITY_ATTRIBUTES``. This has always been problematic and confusing - and with the addition of HTML attributes for various form fields - having a field with multiple possible inputs is no longer a viable user experience. This is no longer supported, and the LoginForm now declares the ``email`` field to be of type ``EmailField`` which requires a valid (after normalization) email address. The most common usage of this legacy feature was to allow an email or username - Flask-Security now has core support for a ``username`` option - see :py:data:`SECURITY_USERNAME_ENABLE`. Please see :ref:`custom_login_form` for an example of how to replicate the legacy behavior. - Some error messages have changed - ``USER_DOES_NOT_EXIST`` is now returned for any identity error including an empty value. Other: - A very old piece of code in registrable, would immediately commit to the DB when a new user was created. It is now consistent with all other views, and has the caller responsible for committing the transaction - usually by setting up a flask ``after_this_request`` action. This could affect an application that captured the registration signal and stored the ``user`` object for later use - this user object would likely be invalid after the request is finished. - Some fields have custom HTML attributes attached to them (e.g. autocomplete, type, etc). These are stored as part of the form in the ``render_kw`` attribute. This could cause some confusion if an app had its own templates and set different attributes. - The keys for "/tf-rescue" select options have changed to be more 'action' oriented: - `lost_device` -> `email` - `no_mail_access` -> `help` - JSON error responses. **THIS IS A BREAKING CHANGE**. In earlier releases, the JSON error response could have either a `error` key which was for rare cases where there was a single non-form related error, or an `errors` key which was a a dict as defined by WTForms. Now, the `errors` key will contain a list of (localized) messages - both non-form related as well as any form related. The key `field_errors` will contain the dict as specified by WTForms. Please note that starting with WTForms 3.0 form-level errors are supported and show up in the dict with the field name/key of "none". There are no changes to non-error related JSON responses. - Permissions **THIS IS A BREAKING CHANGE**. The Role Model now stores permissions as a list, and requires that the underlying DB ORM map that to a supported DB type. For SQLAlchemy, this is mapped to a comma separated string (as before). For SQLAlchemy DBs the underlying Column type (UnicodeText) didn't change so no data migration should be required. However, the ORM Column type did change and requires the following change to your model:: from flask_security import AsaList from sqlalchemy.ext.mutable import MutableList class Role(Base, RoleMixin): ... permissions = Column(MutableList.as_mutable(AsaList()), nullable=True) ... If your application makes use of Flask-Security's models.fsqla_vX classes - no changes are required. For Mongo, a ListField can be directly used. - CSRF - As mentioned above, it is now required that `FlaskWTF::CSRFProtect()`, if used, must be called PRIOR to initializing Flask-Security. - json_encoder_cls - As mentioned above - Flask-Security initialization no longer accepts overriding the json_encoder class. If this is required, update to Flask >=2.2 and implement Flask's JSONProvider interface. For templates: - Pretty much every template was modified to replace <p> with <div class=xx> to make styling possible and to make more complex forms more readable. - Many forms had places where things weren't properly localizable - that has (hopefully) been fixed. - The ``us_setup.html`` template was modified to add ability to delete an existing set up method. DB Migration ~~~~~~~~~~~~ To use the new WebAuthn feature a new table and two new columns in the User model are required. To ease updates - Flask-Security will automatically create a fs_webauthn_user_handle upon first use for existing users. If you are using Alembic the schema migration is easy:: op.add_column('user', sa.Column('fs_webauthn_user_handle', sa.String(length=64), nullable=True, unique=True)) If you want to allow for empty passwords as part of registration then set :py:data:`SECURITY_PASSWORD_REQUIRED` to ``False``. In addition you need to change your DB schema to allow the ``password`` field to be nullable. Version 4.1.5 ------------- Released July 28, 2022 Fixes +++++ - (:pr:`644`) Fix test and other failures with newer Flask-Login/Werkzeug versions. Version 4.1.4 ------------- Released April 19, 2022 Fixes +++++ - (:issue:`594`) Fix test failures with newer Flask versions. Version 4.1.3 ------------- Released March 2, 2022 Fixes +++++ - (:issue:`581`) Fix bug when attempting to disable register_blueprint. (halali) - (:pr:`539`) Fix example documentation re: generating localized messages. (kazuhei2) - (:pr:`546`) Make roles joinedload compatible with SQLAlchemy 2.0. (keats) - (:pr:`586`) Ship py.typed as part of package. - (:issue:`580`) Improve documentation around use of bleach and include in common install extra. Version 4.1.2 ------------- Released September 22, 2021 Fixes +++++ - (:issue:`526`) default_reauthn_handler doesn't honor SECURITY_URL_PREFIX - (:pr:`528`) Improve German translations (sr-verde) - (:pr:`527`) Fix two-factor sample code (djpnewton) Version 4.1.1 -------------- Released September 10, 2021 Fixes +++++ - (:issue:`518`) Fix corner case where Security object was being reused in tests. - (:issue:`512`) If USERNAME_ENABLE is set, change LoginForm field from EmailField to StringField. Also - dynamically add fields to Login and Registration forms rather than always having them - this made the RegistrationForm much simpler. - (:issue:`516`) Improved username feature handling solved issue of always requiring bleach. - (:issue:`513`) Improve documentation of default username validation. Version 4.1.0 ------------- Released July 23, 2021 Features ++++++++ - (:issue:`474`) Add public API and CLI command to change a user's password. - (:issue:`140`) Add type hints. Please note that many of the packages that flask-security depends on aren't typed yet - so there are likely errors in some of the types. - (:issue:`466`) Add first-class support for using username for signing in. Fixes +++++ - (:issue:`483`) 4.0 doesn't accept 3.4 authentication tokens. (kuba-lilz) - (:issue:`490`) Flask-Mail sender name can be a tuple. (hrishikeshrt) - (:issue:`486`) Possible open redirect vulnerability. - (:pr:`478`) Improve/update German translation. (sr-verde) - (:issue:`488`) Improve handling of Babel packages. - (:pr:`496`) Documentation improvements, distribution extras, fix single message override. - (:issue:`497`) Improve cookie handling and default ``samesite`` to ``Strict``. Backwards Compatibility Concerns +++++++++++++++++++++++++++++++++ - (:pr:`488`) In 4.0.0, with the addition of Flask-Babel support, Flask-Security enforced that if it could import either Flask-Babel or Flask-BabelEx, that those modules had been initialized as proper Flask extensions. Prior to 4.0.0, just Flask-BabelEx was supported - and that didn't require any explicit initialization. Flask-Babel DOES require explicit initialization. However for some applications that don't completely control their environment (such as system pre-installed versions of python) this caused applications that didn't even want translation services to fail on startup. With this release, Flask-Security still attempts to import one or the other package - however if those modules are NOT initialized, Flask-Security will simply ignore them and no translations will occur. - (:issue:`497`) The CSRF_COOKIE and TWO_FACTOR_VALIDITY cookie had their defaults changed to set ``samesite=Strict``. This follows the Flask-Security goal of making things more secure out-of-the-box. - (:issue:`140`) Type hinting. For the most part this of course has no runtime effects. However, this required a fairly major overhaul of how Flask-Security is initialized in order to provide valid types for the many constructor attributes. There are no known compatability concerns - however initialization used to convert all arguments into kwargs then add those as attributes and merge with application constants. That no longer happens and it is possible that some corner cases don't behave precisely as they did before. Version 4.0.1 ------------- Released April 2, 2021 Features ++++++++ Fixes +++++ - (:issue:`461`) 4.0 doesn't accept 3.4 authentication tokens. (kuba-lilz) - (:issue:`460`) 2-fa error: Failed to send code - improved documentation and debuggability. - (:issue:`454`) 2-fa error: TypeError - fixed documentation. - (:issue:`443`) Calling create user without any arguments - fixed underlying cause of translating form errors in the CLI. - (:issue:`442`) Email validation confusion - added documentation. - (:issue:`450`) Add documentation on how to override specific error messages. - (:pr:`439`) Don't install global-scope tests. (mgorny) - (:pr:`470`) Add note about updating DB using MySQL. (jugmac00) - (:pr:`468`) Fix documentation - uia_phone_number should be uia_phone_mapper. (dvrg) - (:pr:`457`) Improve chinese translations. (zxjlm) - (:pr:`453`) Improve basque and spanish translations. (mmozos) - (:pr:`448`) Add Afrikaans translations. (lonelyvikingmichael) - (:pr:`467`) Add Blinker as explicit dependency, improve/fix celery usage docs, dont require pyqrcode unless authenticator configured, improve SMS configuration variables documentation. Version 4.0.0 ------------- Released January 26, 2021 **PLEASE READ CHANGE NOTES CAREFULLY - THERE ARE LIKELY REQUIRED CHANGES YOU WILL HAVE TO MAKE TO EVEN START YOUR APPLICATION WITH 4.0** Start Here +++++++++++ - Your UserModel must contain ``fs_uniquifier`` - Either uninstall Flask-BabelEx (if you don't need translations) or add either Flask-Babel (>=2.0) or Flask-BabelEx to your dependencies AND be sure to initialize it in your app. - Add Flask-Mail to your dependencies. - If you have unicode emails or passwords read change notes below. Version 4.0.0rc2 ---------------- Released January 18, 2021 Features & Cleanup +++++++++++++++++++ - Removal of python 2.7 and <3.6 support - Removal of token caching feature (a relatively new feature that had some systemic issues) - (:pr:`328`) Remove dependence on Flask-Mail and refactor. - (:pr:`335`) Remove two-factor `/tf-confirm` endpoint and use generic `freshness` mechanism. - (:pr:`336`) Remove ``SECURITY_BACKWARDS_COMPAT_AUTH_TOKEN_INVALID(ATE)``. In addition to not making sense - the documentation has never been correct. - (:pr:`339`) Require ``fs_uniquifier`` in the UserModel and stop using/referencing the UserModel primary key. - (:pr:`349`) Change ``SECURITY_USER_IDENTITY_ATTRIBUTES`` configuration variable semantics. - Remove (all?) requirements around having an 'email' column in the UserModel. API change - JSON SPA redirects used to always include a query param 'email=xx'. While that is still sent (if and only if) the UserModel contains an 'email' columns, a new query param 'identity' is returned which returns the value of :meth:`.UserMixin.calc_username()`. - (:pr:`382`) Improvements and documentation for two-factor authentication. - (:pr:`394`) Add support for email validation and normalization (see :class:`.MailUtil`). - (:issue:`231`) Normalize unicode passwords (see :class:`.PasswordUtil`). - (:issue:`391`) Option to redirect to `/confirm` if user hits an endpoint that requires confirmation. New option :py:data:`SECURITY_REQUIRES_CONFIRMATION_ERROR_VIEW` which if set and the user hits the `/login`, `/reset`, or `/us-signin` endpoint, and they require confirmation the response will be a redirect. (SnaKyEyeS) - (:issue:`366`) Allow redirects on sub-domains. Please see :py:data:`SECURITY_REDIRECT_ALLOW_SUBDOMAINS`. (willcroft) - (:pr:`376`) Have POST redirects default to Flask's ``APPLICATION_ROOT``. Previously the default configuration was ``/``. Now it first looks at Flask's `APPLICATION_ROOT` configuration and uses that (which also by default is ``/``. (tysonholub) - (:pr:`401`) Add 2FA Validity Window so an application can configure how often the second factor has to be entered. (baurt) - (:pr:`403`) Add HTML5 Email input types to email fields. This has some backwards compatibility concerns outlined below. (drola) - (:pr:`413`) Add hy_AM translations. (rudolfamirjanyan) - (:pr:`410`) Add Basque and fix Spanish translations. (mmozos) - (:pr:`408`) Polish translations. (kamil559) - (:pr:`390`) Update ru_RU translations. (TitaniumHocker) Fixed +++++ - (:issue:`389`) Fixes for translations. First - email subjects were never being translated. Second, converted all templates to use _fsdomain(xx) rather than _(xx) so that they get translated regardless of the app's domain. - (:issue:`381`) Support Flask-Babel 2.0 which has backported Domain support. Flask-Security now supports Flask-Babel (>=2.00), Flask-BabelEx, as well as no translation support. Please see backwards compatibility notes below. - (:pr:`352`) Fix issue with adding/deleting permissions - all mutating methods must be at the datastore layer so that db.put() can be called. Added :meth:`.UserDatastore.add_permissions_to_role` and :meth:`.UserDatastore.remove_permissions_from_role`. The methods `.RoleMixin.add_permissions` and `.RoleMixin.remove_permissions` have been deprecated. - (:issue:`395`) Provide ability to change table names for User and Role tables in the fsqla model. - (:issue:`338`) All sessions are invalidated when a user changes or resets their password. This is accomplished by changing the user's `fs_uniquifier`. The user is automatically re-logged in (and a new session created) after a successful change operation. - (:issue:`418`) Two-factor (and to a lesser extent unified sign in) QRcode fetching wasn't protected via CSRF. The fix makes things secure and simpler (always good); however read below for compatibility concerns. In addition, the elements that make up the QRcode (key, username, issuer) area also made available to the form and returned as part of the JSON return value - this allows for manual or other ways to initialize the authenticator app. - (:issue:`421`) GET on `/login` and `/change` could return the callers authentication_token. This is a security concern since GETs don't have CSRF protection. This bug was introduced in 3.3.0. Backwards Compatibility Concerns +++++++++++++++++++++++++++++++++ - (:pr:`328`) Remove dependence on Flask-Mail and refactor. The ``send_mail_task`` and ``send_mail`` methods as part of Flask-Security initialization have been removed and replaced with a new :class:`.MailUtil` class. The utility method :func:`.send_mail` can still be used. If your application didn't use either of the deprecated methods, then the only change required is to add Flask-Mail to your package requirements (since Flask-Security no longer lists it). Please see the :ref:`emails_topic` for updated examples. - (:pr:`335`) Convert two-factor setup flow to use the freshness feature rather than its own verify password endpoint. This COMPLETELY removes the ``/tf-confirm`` endpoint and associated form: ``two_factor_verify_password_form``. Now, when /tf-setup is invoked, the :meth:`flask_security.check_and_update_authn_fresh` is invoked, and if the current session isn't 'fresh' the caller will be redirected to a verify endpoint (either :py:data:`SECURITY_VERIFY_URL` or :py:data:`SECURITY_US_VERIFY_URL`). The simplest change would be to call ``/verify`` everywhere the application used to call ``/tf-confirm``. - (:pr:`339`) Require ``fs_uniquifier``. In 3.3 the ``fs_uniquifier`` was added in the UserModel to fix the slow authentication token issue. In 3.4 the ``fs_uniquifier`` was used to implement Flask-Login's `Alternative Token` feature - thus decoupling the primary key (id) from any security context. All along, there have been a few issues with applications not wanting to use the name 'id' in their model, or wanting a different type for their primary key. With this change, Flask-Security no longer interprets or uses the UserModel primary key - just the ``fs_uniquifier`` field. See the changes section for 3.3 for information on how to do the schema and data upgrades required to add this field. There is also an API change - the JSON response (via UserModel.get_security_payload()) returned the ``user.id`` field. With this change the default is an empty directory - override :meth:`.UserMixin.get_security_payload()` to return any portion of the UserModel you need. - (:pr:`349`) :py:data:`SECURITY_USER_IDENTITY_ATTRIBUTES` has changed syntax and semantics. It now contains the combined information from the old ``SECURITY_USER_IDENTITY_ATTRIBUTES`` and the newly introduced in 3.4 :py:data:`SECURITY_USER_IDENTITY_MAPPINGS`. This enabled changing the underlying way we validate credentials in the login form and unified sign in form. In prior releases we simply tried to look up the form value as the PK of the UserModel - this often failed and then looped through the other ``SECURITY_USER_IDENTITY_ATTRIBUTES``. This had a history of issues, including many applications not wanting to have a standard PK for the user model. Now, using the mapping configuration, the UserModel attribute/column the input corresponds to is determined, then the UserModel is queried specifically for that *attribute:value* pair. If you application didn't change the variable, no modifications are required. - (:pr:`354`) The :class:`flask_security.PhoneUtil` is now initialized as part of Flask-Security initialization rather than ``@app.before_first_request`` (since that broke the CLI). Since it isn't called in an application context, the *app* being initialized is passed as an argument to *__init__*. - (:issue:`381`) When using Flask-Babel (>= 2.0) it is required that the application initialize Flask-Babel (e.g. Babel(app)). Flask-BabelEx would self-initialize so it didn't matter. Flask-Security will throw a run time error upon first request if Flask-Babel OR FLask-BabelEx is installed, but not initialized. Also, Flask-Security no longer has a dependency on either Flask-Babel or Flask-BabelEx - if neither are installed, it falls back to a dummy translation. *If your application expects translation services, it must specify the appropriate* *dependency AND initialize it.* - (:pr:`394`) Email input is now normalized prior to being stored in the DB. Previously, it was validated, but the raw input was stored. Normalization and validation rely on the `email_validator <https://pypi.org/project/email-validator/>`_ package. The :class:`.MailUtil` class provides the interface for normalization and validation - allowing all this to be customized. If you have unicode local or domain parts - existing users may have difficulties logging in. Administratively you need to read each user record, normalize the email (see :class:`.MailUtil`), and write it back. - (:issue:`381`) Passwords are now, by default, normalized using Python's unicodedata.normalize() method. The :py:data:`SECURITY_PASSWORD_NORMALIZE_FORM` defaults to "NKFD". This brings Flask-Security in line with the NIST recommendations outlined in `Memorized Secret Verifiers <https://pages.nist.gov/800-63-3/sp800-63b.html#sec5>`_ If your users have unicode passwords they may have difficulty authenticating. You can turn off this normalization or have your users reset their passwords. Password normalization and validation has been encapsulated in a new :class:`.PasswordUtil` class. This replaces the method ``password_validator`` introduced in 3.4.0. - (:pr:`403`) By default all forms that have an email as input now use the wtforms html5 ``EmailField``. For most applications this will make the user experience slightly nicer - especially for mobile devices. Some applications use the email form field for other identity attributes (such as username). If your application does this you will probably need to subclass ``LoginForm`` and change the email type back to StringField. - (:issue:`338`) By default, both passwords and authentication tokens use the same attribute ``fs_uniquifier`` to uniquely identify the user. This means that if the user changes or resets their password, all authentication tokens also become invalid. This could be viewed as a feature or a bug. If this behavior isn't desired, add another uniquifier: ``fs_token_uniquifier`` to your UserModel and that will be used to generate authentication tokens. - (:issue:`418`) Fix CSRF vulnerability w.r.t. getting QRcodes. Both two-factor and unified-signup had a separate GET endpoint to fetch the QRcode when setting up an authenticator app. GETS don't have any CSRF protection. Both of those endpoints have been completely removed, and the QRcode is embedded in a successful POST of the setup form. The changes to the templates are minimal and of course if you didn't override the template - there is no compatibility concern. - (:issue:`421`) Fix CSRF vulnerability on `/login` and `/change` that could return the callers authentication token. Now, callers can only get the authentication token on successful POST calls. Version 3.4.5 -------------- Released January 8, 2021 Security Vulnerability Fix. Two CSRF vulnerabilities were reported: `qrcode`_ and `login`_. This release fixes the more severe of the 2 - the `/login` vulnerability. The QRcode issue has a much smaller risk profile since a) it is only for two-factor authentication using an authenticator app b) the qrcode is only available during the time the user is first setting up their authentication app. The QRcode issue has been fixed in 4.0. .. _qrcode: https://github.com/pallets-eco/flask-security/issues/418 .. _login: https://github.com/pallets-eco/flask-security/issues/421 Fixed +++++ - (:issue:`421`) GET on `/login` and `/change` could return the callers authentication_token. This is a security concern since GETs don't have CSRF protection. This bug was introduced in 3.3.0. Backwards Compatibility Concerns ++++++++++++++++++++++++++++++++ - (:issue:`421`) Fix CSRF vulnerability on `/login` and `/change` that could return the callers authentication token. Now, callers can only get the authentication token on successful POST calls. Version 3.4.4 -------------- Released July 27, 2020 Bug/regression fixes. Fixed +++++ - (:issue:`359`) Basic Auth broken. When the unauthenticated handler was changed to provide a more uniform/consistent response - it broke using Basic Auth from a browser, since it always redirected rather than returning 401. Now, if the response headers contain ``WWW-Authenticate`` (which is set if ``basic`` @auth_required method is used), a 401 is returned. See below for backwards compatibility concerns. - (:pr:`362`) As part of figuring out issue 359 - a redirect loop was found. In release 3.3.0 code was put in to redirect to :py:data:`SECURITY_POST_LOGIN_VIEW` when GET or POST was called and the caller was already authenticated. The method used would honor the request ``next`` query parameter. This could cause redirect loops. The pre-3.3.0 behavior of redirecting to :py:data:`SECURITY_POST_LOGIN_VIEW` and ignoring the ``next`` parameter has been restored. - (:issue:`347`) Fix peewee. Turns out - due to lack of unit tests - peewee hasn't worked since 'permissions' were added in 3.3. Furthermore, changes in 3.4 around get_id and alternative tokens also didn't work since peewee defines its own `get_id` method. Compatibility Concerns ++++++++++++++++++++++ In 3.3.0, :meth:`flask_security.auth_required` was changed to add a default argument if none was given. The default include all current methods - ``session``, ``token``, and ``basic``. However ``basic`` really isn't like the others and requires that we send back a ``WWW-Authenticate`` header if authentication fails (and return a 401 and not redirect). ``basic`` has been removed from the default set and must once again be explicitly requested. Version 3.4.3 ------------- Released June 12, 2020 Minor fixes for a regression and a couple other minor changes Fixed +++++ - (:issue:`340`) Fix regression where tf_phone_number was required, even if SMS wasn't configured. - (:pr:`342`) Pick up some small documentation fixes from 4.0.0. Version 3.4.2 ------------- Released May 2, 2020 Only change is to move repo to the Flask-Middleware github organization. Version 3.4.1 -------------- Released April 22, 2020 Fix a bunch of bugs in new unified sign in along with a couple other major issues. Fixed +++++ - (:issue:`298`) Alternative ID feature ran afoul of postgres/psycopg2 finickiness. - (:issue:`300`) JSON 401 responses had WWW-Authenticate Header attached - that caused browsers to pop up their own login/password form. Not what applications want. - (:issue:`280`) Allow admin/api to setup TFA (and unified sign in) out of band. Please see :meth:`.UserDatastore.tf_set`, :meth:`.UserDatastore.tf_reset`, :meth:`.UserDatastore.us_set`, :meth:`.UserDatastore.us_reset` and :meth:`.UserDatastore.reset_user_access`. - (:pr:`305`) We used form._errors which wasn't very pythonic, and it was removed in WTForms 2.3.0. - (:pr:`310`) WTForms 2.3.0 made email_validator optional - we need it. Version 3.4.0 ------------- Released March 31, 2020 Features ++++++++ - (:pr:`257`) Support a unified sign in feature. Please see :ref:`configuration:unified signin`. - (:pr:`265`) Add phone number validation class. This is used in both unified sign in as well as two-factor when using ``sms``. - (:pr:`274`) Add support for 'freshness' of caller's authentication. This permits endpoints to be additionally protected by ensuring a recent authentication. - (:issue:`99`, :issue:`195`) Support pluggable password validators. Provide a default validator that offers complexity and breached support. - (:issue:`266`) Provide interface to two-factor send_token so that applications can provide error mitigation. Defaults to returning errors if can't send the verification code. - (:pr:`247`) Updated all-inclusive data models (fsqlaV2). Add fields necessary for the new unified sign in feature and changed 'username' to be unique (but not required). - (:pr:`245`) Use fs_uniquifier as the default Flask-Login 'alternative token'. Basically this means that changing the fs_uniquifier will cause outstanding auth tokens, session and remember me cookies to be invalidated. So if an account gets compromised, an admin can easily stop access. Prior to this cookies were storing the 'id' which is the user's primary key - difficult to change! (kishi85) Fixed +++++ - (:issue:`273`) Don't allow reset password for accounts that are disabled. - (:issue:`282`) Add configuration that disallows GET for logout. Allowing GET can cause some denial of service issues. The default still allows GET for backwards compatibility. (kantorii) - (:issue:`258`) Reset password wasn't integrated into the two-factor feature and therefore two-factor auth could be bypassed. - (:issue:`254`) Allow lists and sets as underlying permissions. (pffs) - (:issue:`251`) Allow a registration form to have additional fields that aren't part of the user model that are just passed to the user_registered.send signal, where the application can perform arbitrary additional actions required during registration. (kuba-lilz) - (:issue:`249`) Add configuration to disable the 'role-joining' optimization for SQLAlchemy. (pffs) - (:issue:`238`) Fix more issues with atomically setting the new TOTP secret when setting up two-factor. (kishi85) - (:pr:`240`) Fix Quart Compatibility. (ristellise) - (:issue:`232`) CSRF Cookie not being set when using 'Remember Me' cookie to re-sign in. (kishi85) - (:issue:`229`) Two-factor enabled accounts didn't work with the Remember Me feature. (kishi85) As part of adding unified sign in, there were many similarities with two-factor. Some refactoring was done to unify naming, configuration variables etc. It should all be backwards compatible. - In TWO_FACTOR_ENABLED_METHODS "mail" was changed to "email". "mail" will still be honored if already stored in DB. Also "google_authenticator" is now just "authenticator". - TWO_FACTOR_SECRET, TWO_FACTOR_URI_SERVICE_NAME, TWO_FACTOR_SMS_SERVICE, and TWO_FACTOR_SMS_SERVICE_CONFIG have all been deprecated in favor of names that are the same for two-factor and unified sign in. Other changes with possible backwards compatibility issues: - ``/tf-setup`` never did any phone number validation. Now it does. - ``two_factor_setup.html`` template - the chosen_method check was changed to ``email``. If you have your own custom template - be sure make that change. Version 3.3.3 ------------- Released February 11, 2020 Minor changes required to work with latest released Werkzeug and Flask-Login. Version 3.3.2 ------------- Released December 7, 2019 - (:issue:`215`) Fixed 2FA totp secret regeneration bug (kishi85) - (:issue:`172`) Fixed 'next' redirect error in login view - (:issue:`221`) Fixed regressions in login view when already authenticated user again does a GET or POST. - (:issue:`219`) Added example code for unit testing FS protected routes. - (:issue:`223`) Integrated two-factor auth into registration and confirmation. Thanks to kuba-lilz and kishi85 for finding and providing detailed issue reports. In Flask-Security 3.3.0 the login view was changed to allow already authenticated users to access the view. Prior to 3.3.0, the login view was protected with @anonymous_user_required - so any access (via GET or POST) would simply redirect the user to the ``POST_LOGIN_VIEW``. With the 3.3.0 changes, both GET and POST behaved oddly. GET simply returned the login template, and POST attempted to log out the current user, and log in the new user. This was problematic since this couldn't possibly work with CSRF. The old behavior has been restored, with the subtle change that older Flask-Security releases did not look at "next" in the form or request for the redirect, and now, all redirects from the login view will honor "next". Version 3.3.1 ------------- Released November 16, 2019 - (:pr:`197`) Add `Quart <https://gitlab.com/pgjones/quart/>`_ compatibility (Ristellise) - (:pr:`194`) Add Python 3.8 support into CI (jdevera) - (:pr:`196`) Improve docs around Single Page Applications and React (acidjunk) - (:issue:`201`) fsqla model was added to __init__.py making Sqlalchemy a required package. That is wrong and has been removed. Applications must now explicitly import from ``flask_security.models`` - (:pr:`204`) Fix/improve examples and quickstart to show one MUST call hash_password() when creating users programmatically. Also show real SECRET_KEYs and PASSWORD_SALTs and how to generate them. - (:pr:`209`) Add argon2 as an allowable password hash. - (:pr:`210`) Improve integration with Flask-Admin. Actually - this PR improves localization support by adding a method ``_fsdomain`` to jinja2's global environment. Added documentation around localization. Version 3.3.0 ------------- Released September 26, 2019 **There are several default behavior changes that might break existing applications. Most have configuration variables that restore prior behavior**. **If you use Authentication Tokens (rather than session cookies) you MUST make a (small) change. Please see below for details.** - (:pr:`120`) Native support for Permissions as part of Roles. Endpoints can be protected via permissions that are evaluated based on role(s) that the user has. - (:issue:`126`, :issue:`93`, :issue:`96`) Revamp entire CSRF handling. This adds support for Single Page Applications and having CSRF protection for browser(session) authentication but ignored for token based authentication. Add extensive documentation about all the options. - (:issue:`156`) Token authentication is slow. Please see below for details on how to enable a new, fast implementation. - (:issue:`130`) Enable applications to provide their own :meth:`.render_json` method so that they can create unified API responses. - (:issue:`121`) Unauthorized callback not quite right. Split into 2 different callbacks - one for unauthorized and one for unauthenticated. Made default unauthenticated handler use Flask-Login's unauthenticated method to make everything uniform. Extensive documentation added. `.Security.unauthorized_callback` has been deprecated. - (:pr:`120`) Add complete User and Role model mixins that support all features. Modify tests and Quickstart documentation to show how to use these. Please see :ref:`responsetopic` for details. - Improve documentation for :meth:`.UserDatastore.create_user` to make clear that hashed password should be passed in. - Improve documentation for :class:`.UserDatastore` and :func:`.verify_and_update_password` to make clear that caller must commit changes to DB if using a session based datastore. - (:issue:`122`) Clarify when to use ``confirm_register_form`` rather than ``register_form``. - Fix bug in 2FA that didn't commit DB after using `verify_and_update_password`. - Fix bug(s) in UserDatastore where changes to user ``active`` flag weren't being added to DB. - (:issue:`127`) JSON response was failing due to LazyStrings in error response. - (:issue:`117`) Making a user inactive should stop all access immediately. - (:issue:`134`) Confirmation token can no longer be reused. Added *SECURITY_AUTO_LOGIN_AFTER_CONFIRM* option for applications that don't want the user to be automatically logged in after confirmation (defaults to True - existing behavior). - (:issue:`159`) The ``/register`` endpoint returned the Authentication Token even though confirmation was required. This was a huge security hole - it has been fixed. - (:issue:`160`) The 2FA totp_secret would be regenerated upon submission, making QRCode not work. (malware-watch) - (:issue:`166`) `default_render_json` uses ``flask.make_response`` and forces the Content-Type to JSON for generating the response (koekie) - (:issue:`166`) *SECURITY_MSG_UNAUTHENTICATED* added to the configuration. - (:pr:`168`) When using the @auth_required or @auth_token_required decorators, the token would be verified twice, and the DB would be queried twice for the user. Given how slow token verification is - this was a significant issue. That has been fixed. - (:issue:`84`) The :func:`.anonymous_user_required` was not JSON friendly - always performing a redirect. Now, if the request 'wants' a JSON response - it will receive a 400 with an error message defined by *SECURITY_MSG_ANONYMOUS_USER_REQUIRED*. - (:pr:`145`) Improve 2FA templates to that they can be localized. (taavie) - (:issue:`173`) *SECURITY_UNAUTHORIZED_VIEW* didn't accept a url (just an endpoint). All other view configurations did. That has been fixed. Possible compatibility issues +++++++++++++++++++++++++++++ - (:pr:`164`) In prior releases, the Authentication Token was returned as part of the JSON response to each successful call to `/login`, `/change`, or `/reset/{token}` API call. This is not a great idea since for browser-based UIs that used JSON request/response, and used session based authentication - they would be sent this token - even though it was likely ignored. Since these tokens by default have no expiration time this exposed a needless security hole. The new default behavior is to ONLY return the Authentication Token from those APIs if the query param ``include_auth_token`` is added to the request. Prior behavior can be restored by setting the *SECURITY_BACKWARDS_COMPAT_AUTH_TOKEN* configuration variable. - (:pr:`120`) :class:`.RoleMixin` now has a method :meth:`.get_permissions` which is called as part each request to add Permissions to the authenticated user. It checks if the RoleModel has a property ``permissions`` and assumes it is a comma separated string of permissions. If your model already has such a property this will likely fail. You need to override :meth:`.get_permissions` and simply return an emtpy set. - (:issue:`121`) Changes the default (failure) behavior for views protected with @auth_required, @token_auth_required, or @http_auth_required. Before, a 401 was returned with some stock html. Now, Flask-Login.unauthorized() is called (the same as @login_required does) - which by default redirects to a login page/view. If you had provided your own `.Security.unauthorized_callback` there are no changes - that will still be called first. The old default behavior can be restored by setting *SECURITY_BACKWARDS_COMPAT_UNAUTHN* to True. Please see :ref:`responsetopic` for details. - (:issue:`127`) Fix for LazyStrings in json error response. The fix for this has Flask-Security registering its own JsonEncoder on its blueprint. If you registered your own JsonEncoder for your app - it will no longer be called when serializing responses to Flask-Security endpoints. You can register your JsonEncoder on Flask-Security's blueprint by sending it as `json_encoder_cls` as part of initialization. Be aware that your JsonEncoder needs to handle LazyStrings (see speaklater). - (:issue:`84`) Prior to this fix - anytime the decorator :func:`.anonymous_user_required` failed, it caused a redirect to the post_login_view. Now, if the caller wanted a JSON response, it will return a 400. - (:issue:`156`) Faster Authentication Token introduced the following non-backwards compatible behavior change: * Since the old Authentication Token algorithm used the (hashed) user's password, those tokens would be invalidated whenever the user changed their password. This is not likely to be what most users expect. Since the new Authentication Token algorithm doesn't refer to the user's password, changing the user's password won't invalidate outstanding Authentication Tokens. The method :meth:`.UserDatastore.set_uniquifier` can be used by an administrator to change a user's ``fs_uniquifier`` - but nothing the user themselves can do to invalidate their Authentication Tokens. Setting the *SECURITY_BACKWARDS_COMPAT_AUTH_TOKEN_INVALIDATE* configuration variable will cause the user's ``fs_uniquifier`` to be changed when they change their password, thus restoring prior behavior. New fast authentication token implementation ++++++++++++++++++++++++++++++++++++++++++++ Current auth tokens are slow because they use the user's password (hashed) as a uniquifier (the user id isn't really enough since it might be reused). This requires checking the (hashed) password against what is in the token on EVERY request - however hashing is (on purpose) slow. So this can add almost a whole second to every request. To solve this, a new attribute in the User model was added - ``fs_uniquifier``. If this is present in your User model, then it will be used instead of the password for ensuring the token corresponds to the correct user. This is very fast. If that attribute is NOT present - then the behavior falls back to the existing (slow) method. DB Migration ~~~~~~~~~~~~ To use the new UserModel mixins or to add the column ``user.fs_uniquifier`` to speed up token authentication, a schema AND data migration needs to happen. If you are using Alembic the schema migration is easy - but you need to add ``fs_uniquifier`` values to all your existing data. You can add code like this to your migrations::update method:: # be sure to MODIFY this line to make nullable=True: op.add_column('user', sa.Column('fs_uniquifier', sa.String(length=64), nullable=True)) # update existing rows with unique fs_uniquifier import uuid user_table = sa.Table('user', sa.MetaData(), sa.Column('id', sa.Integer, primary_key=True), sa.Column('fs_uniquifier', sa.String)) conn = op.get_bind() for row in conn.execute(sa.select([user_table.c.id])): conn.execute(user_table.update().values(fs_uniquifier=uuid.uuid4().hex).where(user_table.c.id == row['id'])) # finally - set nullable to false op.alter_column('user', 'fs_uniquifier', nullable=False) # for MySQL the previous line has to be replaced with... # op.alter_column('user', 'fs_uniquifier', existing_type=sa.String(length=64), nullable=False) Version 3.2.0 ------------- Released June 26th 2019 - (:pr:`80`) Support caching of authentication token (eregnier `opr #839 <https://github.com/mattupstate/flask-security/pull/839>`_). This adds a new configuration variable *SECURITY_USE_VERIFY_PASSWORD_CACHE* which enables a cache (with configurable TTL) for authentication tokens. This is a big performance boost for those accessing Flask-Security via token as opposed to session. - (:pr:`81`) Support for JSON/Single-Page-Application. This completes support for non-form based access to Flask-Security. See PR for details. (jwag956) - (:pr:`79` Add POST logout to enhance JSON usage (jwag956). - (:pr:`73`) Fix get_user for various DBs (jwag956).

Possible compatibility issues: - #487 - prior to this, render_template() was overridable for views, but not emails. If anyone actually relied on this behavior, this has changed. - #703 - get factory pattern working again. There was a very complex dance between Security() instantiation and init_app regarding kwargs. This has been rationalized (hopefully). - #679 - SqlAlchemy SQL improvement. It is possible you will get the following error:: Got exception during processing: <class 'sqlalchemy.exc.InvalidRequestError'> - 'User.roles' does not support object population - eager loading cannot be applied. This is likely solvable by removing ``lazy='dynamic'`` from your Role definition. Performance improvements: - #679 - for sqlalchemy, for each request, there would be 2 DB accesses - now there is one. Testing: For datastores operations, Sqlalchemy, peewee, pony were all tested against sqlite, postgres, and mysql real databases.

If you would like add features or fix bugs, please review the information below. One source of history or ideas are the `bug reports`_. There you can find ideas for requested features, or the remains of rejected ideas. If you have a 'big idea' - please file an issue first so it can be discussed prior to you spending a lot of time developing. New features need to be generally useful - if your feature has limited applicability, consider making a small change that ENABLES your feature, rather than trying to get the entire feature into Flask-Security. .. _bug reports: https://github.com/pallets-eco/flask-security/issues Checklist --------- * All new code and bug fixes need unit tests * If you change/add to the external API be sure to update docs/openapi.yaml * Additions to configuration variables and/or messages must be documented * Make sure any new public API methods have good docstrings, are picked up by the api.rst document, and are exposed in __init__.py if appropriate. * Add appropriate info to CHANGES.rst Getting the code ---------------- The code is hosted on a GitHub repo at https://github.com/pallets-eco/flask-security. To get a working environment, follow these steps: #. (Optional, but recommended) Create a Python 3.6 (or greater) virtualenv to work in, and activate it. #. Fork the repo `Flask-Security <https://github.com/pallets-eco/flask-security>`_ (look for the "Fork" button). #. Clone your fork locally:: $ git clone https://github.com/<your-username>/flask-security #. Change directory to flask-security:: $ cd flask-security #. Install the requirements:: $ pip install -r requirements/dev.txt #. Install pre-commit hooks:: $ pre-commit install #. Create a branch for local development:: $ git checkout -b name-of-your-bugfix-or-feature #. Develop the Feature/Bug Fix and edit #. Write Tests for your code in:: tests/ #. When done, verify unit tests, syntax etc. all pass:: $ pip install -r requirements/tests.txt $ sphinx-build docs docs/_build/html $ tox -e compile_catalog $ pytest tests $ pre-commit run --all-files #. Use tox:: $ tox # run everything CI does $ tox -e py38-low # make sure works with older dependencies $ tox -e style # run pre-commit/style checks #. When the tests are successful, commit your changes and push your branch to GitHub:: $ git add . $ git commit -m "Your detailed description of your changes." $ git push origin name-of-your-bugfix-or-feature #. Submit a pull request through the GitHub website. #. Be sure that the CI tests and coverage checks pass. Updating the Swagger API document ---------------------------------- When making changes to the external API, you need to update the openapi.yaml formal specification. To do this - install the swagger editor locally:: $ npm -g install swagger-editor-dist http-server Then in a browser navigate to:: file:///usr/local/lib/node_modules/swagger-editor-dist/index.html# Edit - it is a WYSIWYG editor and will show you errors. Once you save (as yaml) you need to look at what it will render as:: $ sphinx-build docs docs/_build/html $ http-server -p 8081 Then in your browser navigate to:: http://localhost:8081/docs/_build/html/index.html or http://localhost:8081/docs/_build/html/_static/openapi_view.html Please note that changing ``openapi.yaml`` won't re-trigger a docs build - so you might have to manually delete ``docs/_build``. Updating Translations --------------------- If you change any translatable strings (such as new messages, modified forms, etc.) you need to re-generate the translations:: $ tox -e extract_messages $ tox -e update_catalog $ tox -e compile_catalog Testing ------- Unit tests are critical since Flask-Security is a piece of middleware. They also help other contributors understand any subtleties in the code and edge conditions that need to be handled. Datastore +++++++++ By default the unit tests use an in-memory sqlite DB to test datastores (except for MongoDatastore which uses mongomock). While this is sufficient for most changes, changes to the datastore layer require testing against a real DB (the CI tests test against postgres). It is easy to run the unit tests against a real DB instance. First of course install and start the DB locally then:: # For postgres pytest --realdburl postgresql://<user>@localhost/ # For mysql pytest --realdburl "mysql+pymysql://root:<password>@localhost/" # For mongodb pytest --realmongodburl "localhost" Views +++++ Much of Flask-Security is concerned with form-based views. These can be difficult to test especially translations etc. In the tests directory is a stand-alone Flask application ``view_scaffold.py`` that can be run and you can point your browser to it and walk through the various views. ������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������flask-security-5.6.1/LICENSE.txt��������������������������������������������������������������������0000664�0000000�0000000�00000002137�14766164353�0016335�0����������������������������������������������������������������������������������������������������ustar�00root����������������������������root����������������������������0000000�0000000������������������������������������������������������������������������������������������������������������������������������������������������������������������������MIT License Copyright (C) 2012-2021 by Matthew Wright Copyright (C) 2019-2025 by Chris Wagner Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

All Flask-Security signals are compatible with Blinker's async implementation. See `Blinker async`_ .. tip:: Remember to add ``**extra_args`` to your signature so that if we add additional parameters in the future your code doesn't break. See the documentation for the signals provided by the Flask-Login and Flask-Principal extensions. In addition to those signals, Flask-Security sends the following signals. .. data:: user_authenticated Sent when a user successfully authenticates. In addition to the app (which is the sender), it is passed `user`, and `authn_via` arguments. The `authn_via` argument specifies how the user authenticated - it will be a list with possible values of ``password``, ``sms``, ``authenticator``, ``email``, ``confirm``, ``reset``, ``register``. .. versionadded:: 3.4.0 .. data:: user_unauthenticated Sent when a user fails to authenticate. It is sent from the `default_unauthn_handler`. It is passed the app (which is the sender). .. versionadded:: 5.4.0 .. data:: user_registered Sent when a user registers on the site. In addition to the app (which is the sender), it is passed `user`, `confirm_token` (deprecated), `confirmation_token` and `form_data` arguments. `form_data` is a dictionary representation of registration form's content received with the registration request. .. data:: user_not_registered Sent when a user attempts to register, but is already registered. This is ONLY sent when :py:data:`SECURITY_RETURN_GENERIC_RESPONSES` is enabled. It is passed the following arguments: * `user` - The existing user model * `existing_email` - True if attempting to register an existing email * `existing_username`- True if attempting to register an existing username * `form_data` - the entire contents of the posted request form .. versionadded:: 5.0.0 .. data:: user_confirmed Sent when a user is confirmed.

The following configuration values are used by Flask-Security: Core -------------- These configuration keys are used globally across all features. .. py:data:: SECRET_KEY This is actually part of Flask - but is used by Flask-Security to sign all tokens. It is critical this is set to a strong value. For python3 consider using: ``secrets.token_urlsafe()`` .. py:data:: SECRET_KEY_FALLBACKS This is part of Flask (>=3.1) but can be used by Flask-Security to unsign tokens. See Flask documentation https://flask.palletsprojects.com/en/stable/config/#SECRET_KEY_FALLBACKS .. versionadded:: 5.6.0 .. py:data:: SECURITY_BLUEPRINT_NAME Specifies the name for the Flask-Security blueprint. Default: ``"security"``. .. py:data:: SECURITY_URL_PREFIX Specifies the URL prefix for the Flask-Security blueprint. Default: ``None``. .. py:data:: SECURITY_STATIC_FOLDER Specifies the folder name for static files (webauthn). Default: ``"static"``. .. versionadded:: 5.1.0 .. py:data:: SECURITY_STATIC_FOLDER_URL Specifies the URL for static files used by Flask-Security (webauthn). See Flask documentation https://flask.palletsprojects.com/en/latest/blueprints/#static-files Default: ``"/fs-static"``. .. versionadded:: 5.1.0 .. py:data:: SECURITY_SUBDOMAIN Specifies the subdomain for the Flask-Security blueprint. If your authenticated content is on a different subdomain, also enable :py:data:`SECURITY_REDIRECT_ALLOW_SUBDOMAINS`. Default: ``None``. .. py:data:: SECURITY_FLASH_MESSAGES Specifies whether or not to flash messages for actions certain endpoint perform. Normally Flash-Security views will flash informational or error messages only when the operation results in a redirect. Default: ``True``. .. py:data:: SECURITY_I18N_DOMAIN Specifies the name for domain used for translations. Default: ``"flask_security"``. .. py:data:: SECURITY_I18N_DIRNAME Specifies the directory containing the ``MO`` files used for translations. When using flask-babel this can also be a list of directory names - this enables application to override a subset of messages if desired. The default ``builtin`` uses translations shipped with Flask-Security. Default: ``"builtin"``. .. versionchanged:: 5.2.0 "builtin" is a special name which will be interpreted as the ``translations`` directory within the installation of Flask-Security. .. py:data:: SECURITY_TOKEN_AUTHENTICATION_KEY Specifies the query string parameter to read when using token authentication. Default: ``"auth_token"``. .. py:data:: SECURITY_TOKEN_AUTHENTICATION_HEADER Specifies the HTTP header to read when using token authentication. Default: ``"Authentication-Token"``. .. py:data:: SECURITY_TOKEN_MAX_AGE Specifies the number of seconds before an authentication token expires. Default: ``None``, meaning the token never expires. .. py:data:: SECURITY_TOKEN_EXPIRE_TIMESTAMP A callable that returns a unix timestamp in the future when this specific authentication token should expire. Returning 0 means no expiration. It is passed the currently authenticated User so any fields can be used to customize an expiration time. Of course it is called in a request context so any information about the current request can also be used. If BOTH this and :data:`SECURITY_TOKEN_MAX_AGE` are set - the shorter is used. .. note:: These 2 expiry options work differently - with this one, the actual expire timestamp is in the auth_token. The signed token (using itsdangerous) has the timestamp the token was generated. On validation, that is checked against ``SECURITY_TOKEN_MAX_AGE``. So for MAX_AGE, at the time of validation, the token hasn't yet been associated with a User. Default: ``lambda user: 0`` .. py:data:: SECURITY_EMAIL_VALIDATOR_ARGS Email address are validated and normalized via the ``mail_util_cls`` which defaults to :class:`.MailUtil`. That uses the `email_validator`_ package whose methods have configurable options - these can be set here and will be passed in. For example setting this to: ``{"check_deliverability": False}`` is useful when unit testing if the emails are fake. ``mail_util_cls`` has 2 methods - ``normalize`` and ``validate``. Both ensure the passed value is a valid email address, and returns a normalized version. ``validate`` additionally, by default, verifies that the email address can likely actually receive an email. Default: ``None``, meaning use the defaults from email_validator package. .. versionadded:: 4.0.0 .. _email_validator: https://pypi.org/project/email-validator/ .. py:data:: SECURITY_DEFAULT_HTTP_AUTH_REALM Specifies the default authentication realm when using basic HTTP auth. Default: ``Login Required`` .. py:data:: SECURITY_REDIRECT_BEHAVIOR Passwordless login, confirmation, reset password, unified signin, change_email, and oauth signin have GET endpoints that validate the passed token and redirect to an action form. For Single-Page-Applications style UIs which need to control their own internal URL routing these redirects need to not contain forms, but contain relevant information as query parameters. Setting this to ``"spa"`` will enable that behavior. When this is enabled, the following must also be defined: - :py:data:`SECURITY_POST_OAUTH_LOGIN_VIEW` (if :py:data:`SECURITY_OAUTH_ENABLE` is True) - :py:data:`SECURITY_LOGIN_ERROR_VIEW` - :py:data:`SECURITY_CONFIRM_ERROR_VIEW` - :py:data:`SECURITY_POST_CHANGE_EMAIL_VIEW` - :py:data:`SECURITY_CHANGE_EMAIL_ERROR_VIEW` - :py:data:`SECURITY_POST_CONFIRM_VIEW` - :py:data:`SECURITY_RESET_ERROR_VIEW` - :py:data:`SECURITY_RESET_VIEW` Default: ``None`` which is existing html-style form redirects. .. versionadded:: 3.3.0 .. py:data:: SECURITY_REDIRECT_HOST Mostly for development purposes, the UI is often developed separately and is running on a different port than the Flask application. In order to test redirects, the `netloc` of the redirect URL needs to be rewritten. Setting this to e.g. `localhost:8080` does that. .. tip:: Be aware that when this is set, any of the `*_VIEW` configuration variables that are set to URLs and not endpoints, will be redirected to this host. Default: ``None``. .. versionadded:: 3.3.0 .. py:data:: SECURITY_REDIRECT_ALLOW_SUBDOMAINS If ``True`` then subdomains (and the root domain) of the top-level host set by Flask's ``SERVER_NAME`` configuration will be allowed as post-view redirect targets. This is beneficial if you wish to place your authentication on one subdomain and authenticated content on another, for example ``auth.domain.tld`` and ``app.domain.tld``. Default: ``False``. .. versionadded:: 4.0.0 .. py:data:: SECURITY_REDIRECT_BASE_DOMAIN Set the base domain for checking allowable redirects. The intent here is to allow an application to be server on e.g. "flaskapp.my.org" and redirect to "myservice.my.org" (which maybe isn't a Flask app). Flask's SERVER_NAME can't be used to verify redirects in this case. Note that in most cases the application will want to set Flask's SESSION_COOKIE_DOMAIN to be this base domain - otherwise authorization information won't be sent. Default: ``None`` .. versionadded:: 5.5.0 .. py:data:: SECURITY_REDIRECT_ALLOWED_SUBDOMAINS A list of subdomains. Each will be prepended to ``SECURITY_REDIRECT_BASE_DOMAIN`` and checked against the requested redirect. Default: ``[]`` .. versionadded:: 5.5.0 .. note:: The above 4 config options apply BOTH to the handling of ``next`` parameter as well as all the ``XXX_VIEW`` URL configuration options for those views that perform a redirect after processing. .. py:data:: SECURITY_CSRF_PROTECT_MECHANISMS Authentication mechanisms that require CSRF protection. These are the same mechanisms as are permitted in the ``@auth_required`` decorator. Default: ``("basic", "session", "token")``. .. py:data:: SECURITY_CSRF_IGNORE_UNAUTH_ENDPOINTS If ``True`` then CSRF will not be required for endpoints that don't require authentication (e.g. login, logout, register, forgot_password). Default: ``False``. .. py:data:: SECURITY_CSRF_COOKIE_NAME The name for the CSRF cookie. This usually should be dictated by your client-side code - more information can be found at :ref:`csrf_topic` Default: ``None`` - meaning no cookie will be sent. .. py:data:: SECURITY_CSRF_COOKIE A dict that defines the parameters required to set a CSRF cookie. The complete set of parameters is described in Flask's `set_cookie`_ documentation. Default: ``{"samesite": "Strict", "httponly": False, "secure": False}`` .. versionchanged:: 4.1.0 The 'key' attribute was deprecated in favor of a separate configuration variable :data:`SECURITY_CSRF_COOKIE_NAME`. .. py:data:: SECURITY_CSRF_HEADER The HTTP Header name that will contain the CSRF token. ``X-XSRF-Token`` is used by packages such as `axios`_. Default: ``"X-XSRF-Token"``. .. py:data:: SECURITY_CSRF_COOKIE_REFRESH_EACH_REQUEST By default, csrf_tokens have an expiration (controlled by the configuration variable ``WTF_CSRF_TIME_LIMIT``. This can cause CSRF failures if say an application is left idle for a long time. You can set that time limit to ``None`` or have the CSRF cookie sent on every request (which will give it a new expiration time). Default: ``False``. .. py:data:: SECURITY_EMAIL_SENDER Specifies the email address to send emails as. Default: value set to ``MAIL_DEFAULT_SENDER`` if Flask-Mail is used otherwise ``no-reply@localhost``. .. py:data:: SECURITY_USER_IDENTITY_ATTRIBUTES Specifies which attributes of the user object can be used for credential validation. Defines the order and matching that will be applied when validating login credentials (either via standard login form or the unified sign in form). The identity field in the form will be matched in order using this configuration - the FIRST match will then be used to look up the user in the DB. Mapping functions take a single argument - ``identity`` from the form and should return ``None`` if the ``identity`` argument isn't in a format suitable for the attribute. If the ``identity`` argument format matches, it should be returned, optionally having had some normalization performed. The returned result will be used to look up the identity in the UserDataStore using the column name specified in the key. The provided :meth:`flask_security.uia_phone_mapper` for example performs phone number normalization using the ``phonenumbers`` package. .. tip:: If your mapper performs any sort of normalization, make sure you apply the exact same transformation in your form validator when setting the field. .. danger:: Make sure that any attributes listed here are marked Unique in your UserDataStore model. .. danger:: Make sure your mapper methods guard against malicious user input. For example, if you allow ``username`` as an identity method you could use `bleach`_:: def uia_username_mapper(identity): # we allow pretty much anything - but we bleach it. return bleach.clean(identity, strip=True) Default:: [ {"email": {"mapper": uia_email_mapper, "case_insensitive": True}}, ] If you enable :py:data:`SECURITY_UNIFIED_SIGNIN` and set ``sms`` as a :py:data:`SECURITY_US_ENABLED_METHODS` and your `SECURITY_USER_IDENTITY_ATTRIBUTES` contained:: [ {"email": {"mapper": uia_email_mapper, "case_insensitive": True}}, {"us_phone_number": {"mapper": uia_phone_mapper}}, ] Then after the user sets up their SMS - they could login using their phone number and get a text with the authentication code. .. versionchanged:: 4.0.0 Changed from list to list of dict. .. _bleach: https://pypi.org/project/bleach/ .. py:data:: SECURITY_USER_IDENTITY_MAPPINGS .. versionadded:: 3.4.0 .. deprecated:: 4.0.0 Superseded by :py:data:`SECURITY_USER_IDENTITY_ATTRIBUTES` .. py:data:: SECURITY_API_ENABLED_METHODS Various endpoints of Flask-Security require the caller to be authenticated. This variable controls which of the methods - ``token``, ``session``, ``basic`` will be allowed. The default does NOT include ``basic`` since if ``basic`` is in the list, and if the user is NOT authenticated, then the standard/required response of 401 with the ``WWW-Authenticate`` header is returned. This is rarely what the client wants. Default: ``["session", "token"]``. .. versionadded:: 4.0.0 .. py:data:: SECURITY_DEFAULT_REMEMBER_ME Specifies the default "remember me" value used when logging in a user. Default: ``False``. .. py:data:: SECURITY_RETURN_GENERIC_RESPONSES If set to ``True`` Flask-Security will return generic responses to endpoints that could be used to enumerate users. Please see :ref:`generic_responses`. Default: ``False`` .. versionadded:: 5.0.0 .. py:data:: SECURITY_FRESHNESS A timedelta used to protect endpoints that alter sensitive information. This is used to protect the following endpoints: - :py:data:`SECURITY_US_SETUP_URL` - :py:data:`SECURITY_TWO_FACTOR_SETUP_URL` - :py:data:`SECURITY_WAN_REGISTER_URL` - :py:data:`SECURITY_WAN_DELETE_URL` - :py:data:`SECURITY_MULTI_FACTOR_RECOVERY_CODES` - :py:data:`SECURITY_CHANGE_EMAIL_URL` Setting this to a negative number will disable any freshness checking and the endpoints: - :py:data:`SECURITY_VERIFY_URL` - :py:data:`SECURITY_US_VERIFY_URL` - :py:data:`SECURITY_US_VERIFY_SEND_CODE_URL` - :py:data:`SECURITY_WAN_VERIFY_URL` won't be registered. Setting this to 0 results in undefined behavior. Please see :meth:`flask_security.check_and_update_authn_fresh` for details. .. note:: The timestamp of when the caller/user last successfully authenticated is stored in the session as well as authentication token. Default: timedelta(hours=24) .. versionadded:: 3.4.0 .. py:data:: SECURITY_FRESHNESS_GRACE_PERIOD A timedelta that provides a grace period when altering sensitive information. This ensures that multi-step operations don't get denied because the session/token happens to expire mid-step. Note that this is not implemented for freshness information carried in the auth token. N.B. To avoid strange behavior, be sure to set the grace period less than the freshness period. Please see :meth:`flask_security.check_and_update_authn_fresh` for details. Default: timedelta(hours=1) .. versionadded:: 3.4.0 .. py:data:: SECURITY_FRESHNESS_ALLOW_AUTH_TOKEN Controls whether the freshness data set in the auth token can be used to satisfy freshness checks. Some applications might want to force freshness protected endpoints to always use browser based access with sessions - they should set this to ``False``. Default: ``True`` .. versionadded:: 5.5.0 Core - Passwords and Tokens ---------------------------- .. py:data:: SECURITY_PASSWORD_HASH Specifies the password hash algorithm to use when hashing passwords. Recommended values for production systems are ``argon2``, ``bcrypt``, or ``pbkdf2_sha512``. Some algorithms require the installation of a backend package (e.g. `bcrypt`_, `argon2`_). Default: ``"argon2"``. .. versionchanged:: 5.5.0 Default changed from ``bcrypt`` to ``argon2``. .. py:data:: SECURITY_PASSWORD_SCHEMES List of supported password hash algorithms. ``SECURITY_PASSWORD_HASH`` must be from this list. Passwords encrypted with any of these schemes will be honored. This is passed directly to `passlib's CryptoContext`_. .. py:data:: SECURITY_DEPRECATED_PASSWORD_SCHEMES List of password hash algorithms that are considered weak and will be accepted, however on first use, will be re-hashed to the current setting of ``SECURITY_PASSWORD_HASH``. This is passed directly to `passlib's CryptoContext`_. Default: ``["auto"]`` which means any password found that wasn't hashed using ``SECURITY_PASSWORD_HASH`` will be re-hashed. .. py:data:: SECURITY_PASSWORD_SALT Specifies the HMAC salt. This is required for all schemes that are configured for double hashing. A good salt can be generated using: ``secrets.SystemRandom().getrandbits(128)``. Default: ``None``. .. py:data:: SECURITY_PASSWORD_SINGLE_HASH A list of schemes that should not be hashed twice. By default, passwords are hashed twice, first with :py:data:`SECURITY_PASSWORD_SALT`, and then with a random salt. Default: a list of known schemes not working with double hashing (`django_{digest}`, `plaintext`). .. py:data:: SECURITY_HASHING_SCHEMES List of algorithms used for encrypting/hashing sensitive data within a token (Such as is sent with confirmation or reset password). This is passed directly to `passlib's CryptoContext`_. Default: ``["sha256_crypt", "hex_md5"]``. .. py:data:: SECURITY_DEPRECATED_HASHING_SCHEMES List of deprecated algorithms used for creating and validating tokens. This is passed directly to `passlib's CryptoContext`_. Default: ``["auto"]``. .. versionchanged:: 5.5.0 Default changed from ``hex_md5`` to ``auto``. .. py:data:: SECURITY_PASSWORD_HASH_OPTIONS Specifies additional options to be passed to the hashing method. This is deprecated as of passlib 1.7. .. deprecated:: 3.4.0 see: :py:data:`SECURITY_PASSWORD_HASH_PASSLIB_OPTIONS` .. py:data:: SECURITY_PASSWORD_HASH_PASSLIB_OPTIONS Pass additional options through ``passlib`` to the various hashing methods. This is a dict of the form ``{__
