SCA: security update for Flask-HTTPAuth (GHSA-p44q-vqpr-4xmg)

high Tenable Cloud Security Plugin ID 439542

Description

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

 - Flask-HTTPAuth provides Basic, Digest and Token HTTP authentication for Flask routes. Prior to version
 4.8.1, in a situation where the client makes a request to a token protected resource without passing a
 token, or passing an empty token, Flask-HTTPAuth would invoke the application's token verification
 callback function with the token argument set to an empty string. If the application had any users in its
 database with an empty string set as their token, then it could potentially authenticate the client
 request against any of those users. This issue has been patched in version 4.8.1. (CVE-2026-34531)

Solution

Update the Flask-HTTPAuth library and its related packages to version 4.8.1 or later.
