CVE-2026-81733Public exploitNetwork attack vector

Viewer redirection via tokenless live-control request

Published Aug 28, 2026 · Updated Aug 29, 2026

CSRF in AVideo through 30.0 allows remote attackers to alter a logged-in streamer's live-channel redirect settings via a crafted page. The myLiveControls.save.json.php endpoint accepts customUrl, customMessage, and autoRedirect from a GET request and writes them to users.externalOptions without a CSRF token or origin check. A logged-in streamer must load the attacker's page; subsequent viewers can then be redirected to a phishing site or shown a spoofed message.
