CVE-2026-40911
WWBN AVideo is an open source video platform.
Published Apr 21, 2026 · updated Jun 17, 2026 · wwbn avideo
WWBN AVideo is an open source video platform. In versions 29.0 and prior, the YPTSocket plugin's WebSocket server relays attacker-supplied JSON message bodies to every connected client without sanitizing the or fields. On the client side, contains two sinks fed directly by those relayed fields ( at line 568 and at line 95). Because tokens are minted for anonymous visitors and never revalidated beyond decryption, an unauthenticated attacker can broadcast arbitrary JavaScript that executes in the origin of every currently-connected user (including administrators), resulting in universal account takeover, session theft, and privileged action execution. Commit c08694bf6264eb4decceb78c711baee2609b4efd contains a fix.
