CVE-2026-40926

WWBN AVideo is an open source video platform. In versions 29.0 and prior, three admin-only JSON endpoints — `objects/categoryAddNew.json.php`, `objects/categoryDelete.json.php`, and `objects/pluginRunUpdateScript.json.php` — enforce only a role check (`Category::canCreateCategory()` / `User::isAdmin()`) and perform state-changing actions against the database without calling `isGlobalTokenValid()` or `forbidIfIsUntrustedRequest()`. Peer endpoints in the same directory (`pluginSwitch.json.php`, `pluginRunDatabaseScript.json.php`) do enforce the CSRF token, so the missing checks are an omission rather than a design choice. An attacker who lures a logged-in admin to a malicious page can create, update, or delete categories and force execution of any installed plugin's `updateScript()` method in the admin's session. Commit ee5615153c40628ab3ec6fe04962d1f92e67d3e2 contains a fix.
