Overview
wwbn/avideo is an Audio and Video Platform or simply "A Video Platform".
Affected versions of this package are vulnerable to Arbitrary Code Injection via the msg and callback fields in relayed WebSocket messages, which are processed by client-side eval() sinks. An attacker can execute arbitrary JavaScript code in the browsers of all connected users by sending specially crafted JSON payloads through the WebSocket server. This enables session theft, privilege escalation, and unauthorized actions within the context of affected users, including administrators.
