SCA: security update for phpmyfaq/phpmyfaq, thorsten/phpmyfaq (GHSA-wm8h-26fv-mg7g)

medium Tenable Self-Hosted Container Security Plugin ID 436921

Description

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

 - phpMyFAQ is an open source FAQ web application. Versions 4.0.16 and below have flawed authorization logic
 which exposes the /api/setup/backup endpoint to any authenticated user despite their permissions.
 SetupController.php uses userIsAuthenticated() but does not verify that the requester has
 configuration/admin permissions. Non-admin users can trigger a configuration backup and retrieve its path.
 The endpoint only checks authentication, not authorization, and returns a link to the generated ZIP. This
 issue is fixed in version 4.0.17. (CVE-2026-24421)
