{"id":"CVE-2026-34364","state":"PUBLISHED","title":"AVideo has User Group-Based Category Access Control Bypass via Missing and Broken Group Filtering in categories.json.php","description":"WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `categories.json.php` endpoint, which serves the category listing API, fails to enforce user group-based access controls on categories.
