SCA: security update for Flask-Security-Too (GHSA-hh7m-rx4f-4vpv)

high Tenable Self-Hosted Container Security Plugin ID 415752

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- The Python "Flask-Security-Too" package is used for adding security features to your Flask application. It
is an is a independently maintained version of Flask-Security based on the 3.0.0 version of Flask-
Security. In Flask-Security-Too from version 3.3.0 and before version 3.4.5, the /login and /change
endpoints can return the authenticated user's authentication token in response to a GET request. Since GET
requests aren't protected with a CSRF token, this could lead to a malicious 3rd party site acquiring the
authentication token. Version 3.4.5 and version 4.0.0 are patched. As a workaround, if you aren't using
authentication tokens - you can set the SECURITY_TOKEN_MAX_AGE to "0" (seconds) which should make the
token unusable. (CVE-2021-21241)
