Hi,
The following vulnerability was published for flask-security.
CVE-2021-23385[0]:
| This affects all versions of package Flask-Security. 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.
