Summary

The PayDunya WooCommerce Payment Gateway WordPress plugin through 1.1.6 does not verify the authenticity of incoming payment notifications (CWE-345). Until the gateway is configured, it authenticates them with a value derived from an empty secret that anyone can compute. Unauthenticated attackers can use this to mark arbitrary WooCommerce orders as paid and completed.
