Auth bypass in Wwbn Avideo
CVE-2026-35448
WWBN AVideo is an open source video platform. In versions 26.0 and prior, the BlockonomicsYPT plugin's check.php endpoint returns payment order data for any Bitcoin address without requiring authentication. The endpoint was designed as an AJAX polling helper for the authenticated invoice.php page, but it performs no access control checks of its own. Since Bitcoin addresses are publicly visible on the blockchain, an attacker can query payment records for any address used on the platform.
