Vulnerability Title
CorvusPay WooCommerce Payment Gateway <= 2.7.4 - Missing Authorization to Unauthenticated Arbitrary Order Cancellation via 'order_number' Parameter
Source: CVE Program / CVE List V5
Vulnerability 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. This makes it possible for unauthenticated attackers to cancel any WooCommerce order placed via the CorvusPay payment method by supplying an arbitrary order number to the /wp-json/corvuspay/cancel/ REST endpoint.
