Summary
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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of WWBN/AVideo published their own advisory on GitHub. Reviewed sources take precedence over it.
