CVE-2026-88998 Details
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.
A vulnerability exists in the Tickera WordPress plugin in versions prior to 3.6.0.4, where the plugin fails to properly verify the integrity of incoming payment notifications. The issue arises because the validated signature does not encompass the order details or the payment amount. This flaw enables unauthenticated attackers to fabricate payment confirmations, falsely marking arbitrary orders as paid without actually making a payment.
Users are advised to update the Tickera WordPress plugin to version 3.6.0.4 or later.
