Description
WWBN AVideo contains an authentication failure vulnerability where the video_id_hash credential is a non-expiring, non-revocable bearer token that grants full administrator session access to the video owner's account. Attackers who obtain a video_id_hash can replay it indefinitely to authenticate as the video owner with full privileges, and the credential remains valid even after the owner changes their password.
