What happened

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.

About this data

This record was ingested from a data source. Retrieved: Oct 26, 2026, 23:15 UTC. Ingestion is not an independent editorial investigation.

NVD status: Analyzed. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
