    "title": "AVideo Authentication Bypass via Unkeyed Video Hash Disclosure",
    "summary": "AVideo through commit 9c39d8c8 contains an authentication bypass vulnerability where deduplicateByEncoderQueueId() returns video_id_hash credentials for any video by encoder_queue_id without ownership verification, and useVideoHashOrLogin() converts this hash into passwordless login as the video owner. Attackers with upload permission can retrieve an administrator's video_id_hash by omitting the videos_id parameter, then use that hash in an unauthenticated request to gain administrative session access and modify system configuration.",
