    Open Redirect

    Flask-Security is a Simple security for Flask apps.

    Affected versions of this package are vulnerable to Open Redirect via the the /login and /register routes, using the ?next parameter.

    Note:

    With Werkzeug >=2.1.0 the autocorrect_location_header configuration was changed to False - which means that location headers in redirects are relative by default. Thus, this issue may impact applications that were previously not impacted, if they are using Werkzeug >=2.1.0 as the WSGI layer.

    How to fix Open Redirect?

    There is no fixed version for Flask-Security.

    Timing Attack

    Flask-Security is a Simple security for Flask apps.

    Affected versions of this package are vulnerable to Timing Attack. The time it takes to process a login request is considerably less if the user-specified doesn't exist than if the password is incorrect. This can be used as a user enumeration attack, even if the login error messages were customized to avoid this.

    How to fix Timing Attack?

    A fix was pushed into the master branch but not yet published.

    Open Redirect

    Flask-Security is a Simple security for Flask apps.

    Affected versions of this package are vulnerable to Open Redirect. When using the get_post_logout_redirect and get_post_login_redirect functions, it is possible to bypass URL validation and redirect a user to an arbitrary URL by providing multiple back slashes such as \\\evil.com/path.

    This vulnerability is only exploitable if an alternative WSGI server other than Werkzeug is used, or the default behaviour of Werkzeug is modified using 'autocorrect_location_header=False`.

    Note: Flask-Security is not maintained anymore.

    How to fix Open Redirect?

    There is no fixed version for Flask-Security.
