Open Library Foundation VuFind v11.0.3 and v4.1 is vulnerable to toInorrect Access Control. The application fails to stop processing an incoming request in VuFind\Controller\AbstractBase::validateAccessPermission after it has found that controller level access permissions do not allow access to the requested function. The requester receives a response indicating that access was denied, but the actual function is executed regardless of that.
