Published Oct 14, 2026 · Updated Oct 14, 2026 · Assigned by WPScan

Description

The Tickera WordPress plugin before 3.6.0.4 does not correctly verify the integrity of incoming payment notifications, and the validated signature does not cover the order or the amount, allowing unauthenticated attackers to forge a payment confirmation and mark arbitrary orders as paid without paying.
