CVE-2026-103300 Details
Description
The Eurobank WooCommerce Payment Gateway WordPress plugin through 2.1.1 does not verify that a payment-confirmation request genuinely originates from the payment provider, and ships with the secret that would authenticate it empty by default, allowing unauthenticated attackers to mark any pending order as paid, and to force any order into a failed status without any secret at all.
A vulnerability exists in the Eurobank WooCommerce Payment Gateway WordPress plugin, affecting versions through 2.1.1. The plugin fails to verify the authenticity of payment-confirmation requests from the payment provider and, by default, the authentication secret is empty. This allows unauthenticated attackers to falsely mark pending orders as paid or to change any order status to failed without needing a secret.
