CVE-2026-83595Network attack vectorHinoki check available

State changes via CSRF-unprotected GET requests

Published Sep 1, 2026 · Updated Sep 1, 2026

Cross-site request forgery in WWBN AVideo 29.0 and earlier allows remote attackers to alter application state through crafted GET requests. The plugin/API/set.json.php endpoint accepts state-changing API parameters in GET requests without enforcing CSRF protection. A victim's authenticated browser must request the crafted URL; exploitation deletes videos, deactivates accounts, or modifies playlists.
