CVE-2026-34368

WWBN AVideo is an open source video platform.

Published Mar 27, 2026 · updated Jun 17, 2026 · wwbn avideo

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the method in contains a Time-of-Check-Time-of-Use (TOCTOU) race condition. The method reads the sender's wallet balance, checks sufficiency in PHP, then writes the new balance — all without database transactions or row-level locking. An attacker with multiple authenticated sessions can send concurrent transfer requests that all read the same stale balance, each passing the balance check independently, resulting in only one deduction being applied while the recipient is credited multiple times. Commit 34132ad5159784bfc7ba0d7634bb5c79b769202d contains a fix.
