Vulnerability Vulnerable Version
  • M
Open Redirect

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?

Upgrade Flask-Security-Too to version 5.3.3 or higher.

[,5.3.3)
  • M
Open Redirect

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`.

How to fix Open Redirect?

Upgrade Flask-Security-Too to version 4.1.0 or higher.
