Eupago Gateway For Woocommerce vulnerabilities

The Eupago Gateway plugin for WooCommerce before version 4.7.2 does not properly restrict access to its refund request handler, allowing unauthenticated attackers to initiate refunds against any WooCommerce order using the merchant's payment gateway credentials.

The Eupago Gateway For Woocommerce WordPress plugin from 4.5.0 through 4.7.5 does not verify the authenticity of incoming payment-confirmation webhook requests in some configurations, allowing unauthenticated attackers to forge a payment confirmation and mark a pending order as paid without paying for it.

The Eupago Gateway For Woocommerce plugin contains a missing authorization vulnerability that allows exploiting incorrectly configured access control security levels. The issue affects versions up to and including 4.7.1.
