CVE-2026-9028 - Vulnerability Details

- CorvusPay WooCommerce Payment Gateway <= 2.7.4 - Missing Authorization to Unauthenticated Arbitrary Order Cancellation via 'order_number' Parameter

Description

The CorvusPay WooCommerce Payment Gateway plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.7.4. This is due to the plugin not properly verifying that a user is authorized to perform an action.
