CVE-2026-85154Network attack vectorHinoki check available

Administrator session takeover via replayable video hash

Published Sep 3, 2026 · Updated Sep 3, 2026

Authentication bypass in WWBN AVideo 29.0 and earlier allows remote attackers to assume a video owner's session using video_id_hash. deduplicateByEncoderQueueId() exposes another user's video_id_hash, and useVideoHashOrLogin() accepts the value for passwordless owner login. Possession of the hash grants full administrator access, while password changes neither expire nor revoke the credential.
