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 through the autoEvalCodeOnHTML process. An attacker can execute arbitrary JavaScript code in the browser context of any logged-in user by sending a crafted WebSocket message that bypasses server-side filtering and is relayed to the victim's session. This allows the attacker to perform actions on behalf of the victim, access sensitive data, and potentially escalate privileges if an administrator is targeted.
