CVE-2026-59808

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.

Summary		(es) AVideo a través del commit 9c39d8c8 contiene una vulnerabilidad de omisión de autenticación donde deduplicateByEncoderQueueId() devuelve credenciales video_id_hash para cualquier video por encoder_queue_id sin verificación de propiedad, y useVideoHashOrLogin() convierte este hash en un inicio de sesión sin contraseña como el propietario del video. Los atacantes con permiso de carga pueden recuperar el video_id_hash de un administrador omitiendo el parámetro videos_id, luego usar ese hash en una solicitud no autenticada para obtener acceso a la sesión administrativa y modificar la configuración del sistema.
