CVE-2026-34731Public exploitNetwork attack vector

Unauthenticated stream termination via unprotected RTMP callback

Published Mar 31, 2026 · Updated Mar 31, 2026

Missing authentication in the Live plugin in World Wide Broadcast Network AVideo 26.0 and earlier allows remote attackers to terminate live streams. The on_publish_done.php endpoint accepts an attacker-supplied stream key and marks the matching transmission history record finished without authentication or authorization. Unauthenticated stats.json.php access exposes active keys, so network access to both endpoints enables systematic interruption of active broadcasts.
