Summary

The Cardinity Payment Gateway for WooCommerce WordPress plugin before 3.4.2 does not properly verify the authenticity of the payment notifications it receives, as the secret used to sign them is empty by default, allowing unauthenticated attackers to forge an approved-payment notification and mark arbitrary orders as paid, or force them to failed.

Risk Assessment

An attacker can mark orders as paid without making a payment, leading to financial losses and compromised order data integrity.

Recommendation

Update the Cardinity Payment Gateway for WooCommerce plugin to version 3.4.2 or later and ensure the notification signing secret is set to a non-empty value.
