Upgrade thorsten/phpmyfaq to version 4.2.0-beta or higher.
Overview
thorsten/phpmyfaq is a FAQ system for PHP and MySQL, PostgreSQL and other databases
Affected versions of this package are vulnerable to Improper Privilege Management via the updateUserRights method in UserController.php, where a non-SuperAdmin administrator with the USER_EDIT right can widen their own language-scoped permissions by re-saving the rights they already hold. When user rights are re-saved, the existing per-right language restriction rows are dropped by refuseAllUserRights() before being re-granted, and the code previously failed to re-apply the acting user's own language scope as a ceiling. This allows a language-restricted administrator to escalate their privileges to a broader language scope than originally granted.
