Executive Summary

This vulnerability affects the PayDunya WooCommerce Payment Gateway WordPress plugin up to version 1.1.6. It allows unauthenticated attackers to forge payment notifications and mark arbitrary WooCommerce orders as paid and completed without verification due to an empty secret key used for authentication.

Impact Analysis

Attackers could exploit this to trick your store into processing fake payments, leading to financial losses or incorrect order fulfillment. Since orders appear paid without real transactions, you might ship products without receiving payment.

Mitigation Strategies

Immediately disable the PayDunya WooCommerce Payment Gateway plugin if installed. Update to the latest version if an official fix becomes available. Monitor WooCommerce orders for unauthorized changes to payment status.
