Description
WWBN AVideo through 29.7.1 contains an incorrect authorization vulnerability that allows delegated Videos Admin users to obtain video_id_hash values bound to any video owner via encoder endpoints like aVideoEncoderStatus.json.php. Attackers can request the hash for an administrator-owned video and replay it through useVideoHashOrLogin() for password-less login, gaining plugin upload, configuration, and user management access.
