CVE-2026-34731
AVideo: Unauthenticated Live Stream Termination via RTMP Callback on_publish_done.php
Description
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the AVideo on_publish_done.php endpoint in the Live plugin allows unauthenticated users to terminate any active live stream. The endpoint processes RTMP callback events to mark streams as finished in the database, but performs no authentication or authorization checks before doing so. An attacker can enumerate active stream keys from the unauthenticated stats.json.php endpoint, then send crafted POST requests to on_publish_done.php to terminate any live broadcast. This enables denial-of-service against all live streaming functionality on the platform. At time of publication, there are no publicly available patches.

Action Type Old Value New Value Added Translation Title: AVideo de WWBN, Description: WWBN AVideo es una plataforma de video de código abierto. En las versiones 26.0 y anteriores, el endpoint on_publish_done.php de AVideo en el plugin Live permite a usuarios no autenticados terminar cualquier transmisión en vivo activa. El endpoint procesa eventos de callback RTMP para marcar las transmisiones como finalizadas en la base de datos, pero no realiza comprobaciones de autenticación ni autorización antes de hacerlo. Un atacante puede enumerar claves de transmisión activas desde el endpoint stats.json.php no autenticado, luego enviar solicitudes POST manipuladas a on_publish_done.php para terminar cualquier transmisión en vivo. Esto permite la denegación de servicio contra toda la funcionalidad de transmisión en vivo en la plataforma. En el momento de la publicación, no hay parches disponibles públicamente. -
