Robokassa payment gateway for Woocommerce < 1.8.9 - Unauthenticated Payment Bypass via Forged JWT Callback

Published Sep 17, 2026 · Updated Sep 17, 2026 · Assigned by WPScan

Description

The Robokassa payment gateway for Woocommerce WordPress plugin before 1.8.9 does not verify the authenticity of incoming payment notifications when its non-default deferred-payment feature is enabled, allowing unauthenticated attackers to forge a notification and mark arbitrary WooCommerce orders as paid or on-hold without payment or a valid signature.
