CVE-2026-39368
WWBN AVideo has a Live restream log callback flow enabling stored SSRF to internal services
Description
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the Live restream log callback flow accepted an attacker-controlled restreamerURL and later fetched that stored URL server-side, enabling stored SSRF for authenticated streamers. The vulnerable flow allowed a low-privilege user with streaming permission to store an arbitrary callback URL and trigger server-side requests to loopback or internal HTTP services through the restream log feature.

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 flujo de devolución de llamada del registro de retransmisión en vivo aceptaba una URL de retransmisor (restreamerURL) controlada por el atacante y posteriormente recuperaba esa URL almacenada en el lado del servidor, lo que permitía SSRF almacenado para los streamers autenticados. El flujo vulnerable permitía a un usuario de bajo privilegio con permiso de streaming almacenar una URL de devolución de llamada arbitraria y desencadenar solicitudes del lado del servidor a servicios HTTP internos o de bucle invertido a través de la función de registro de retransmisión. -
