CVE-2026-24421

MEDIUM

6.5

Description

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.
