SSRF in Wwbn Avideo

CVE-2026-39368

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.

Vulnerability class: SSRF (Server-Side Request Forgery)
