Auth bypass in Wwbn Avideo
CVE-2026-33685
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the `plugin/AD_Server/reports.json.php` endpoint performs no authentication or authorization checks, allowing any unauthenticated attacker to extract ad campaign analytics data including video titles, user channel names, user IDs, ad campaign names, and impression/click counts. The HTML counterpart (`reports.php`) and CSV export (`getCSV.php`) both correctly enforce `User::isAdmin()`, but the JSON API was left unprotected. Commit daca4ffb1ce19643eecaa044362c41ac2ce45dde contains a patch.
