CVE-2026-40926 Details
Description
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.
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in WWBN AVideo, an open-source video platform, in versions through 29.0. The issue resides in three admin-only JSON endpoints: 'objects/categoryAddNew.json.php', 'objects/categoryDelete.json.php', and 'objects/pluginRunUpdateScript.json.php'. These endpoints perform state-changing actions on the database but lack proper CSRF protection. While peer endpoints in the same directory do enforce CSRF tokens, the omission in these three endpoints allows an attacker to manipulate categories and execute plugin update scripts by luring a logged-in admin to a malicious page.
The recommended fix is to add a CSRF token validation check to each affected endpoint, similar to the existing checks in 'pluginSwitch.json.php' and 'pluginRunDatabaseScript.json.php'.
