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.
AnalysisAI
phpMyFAQ versions 4.0.16 and below allow authenticated users to access the backup API endpoint without proper authorization checks, enabling them to download configuration files containing sensitive data. The vulnerability stems from incomplete authorization validation in SetupController.php, which only verifies authentication rather than admin permissions. Public exploit code exists for this issue, and no patch is currently available.
