Executive Summary

The vulnerability in the Wizit Gateway for WooCommerce plugin (up to version 1.2.9) allows unauthenticated attackers to cancel arbitrary WooCommerce orders. This happens because the 'handle_checkout_redirecturl_response' function lacks proper authentication and authorization checks, enabling attackers to send crafted requests with valid order IDs to cancel orders without permission.

Mitigation Strategies

Immediate mitigation steps include disabling the Wizit Gateway for WooCommerce plugin until a patched version beyond 1.2.9 is available, or restricting access to the plugin's endpoints to authenticated users only.
