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.

phpMyFAQ is an open source FAQ web application. Versions 4.0.14 and 4.0.15 have a stored cross-site scripting (XSS) vulnerability that allows an attacker to execute arbitrary JavaScript in an administrator’s browser by registering a user whose display name contains HTML entities. When an administrator views the admin user list, the payload is decoded server-side and rendered without escaping, resulting in script execution in the admin context. Version 4.0.16 contains a patch for the issue.

phpMyFAQ is an open source FAQ web application. In versions prior to 4.0.16, an unauthenticated remote attacker can trigger generation of a configuration backup ZIP via `POST /api/setup/backup` and then download the generated ZIP from a web-accessible location. The ZIP contains sensitive configuration files (e.g., `database.php` with database credentials), leading to high-impact information disclosure and potential follow-on compromise. Version 4.0.16 fixes the issue.
