0 CVE-2026-43874 is a high-severity code injection vulnerability in WWBN AVideo versions up to and including 29.0. The issue arises because the server-side mitigation for a previous vulnerability (CVE-2026-40911) only strips malicious payloads in a specific JSON field ($json['msg']), but the relay function uses a different field ($msg['json']) to select outbound messages. An unauthenticated attacker can obtain a WebSocket token, connect to the WebSocket server, and send a specially crafted message that bypasses the stripping mechanism. This message is then relayed verbatim to logged-in users and executed via eval() on the client side, enabling code injection. There is a commit referenced that contains an updated fix, but no official patch or vendor advisory is provided in the data.
