The PayDunya WooCommerce Payment Gateway WordPress plugin through 1.1.6 does not verify the authenticity of incoming payment notifications and, until the gateway is configured, authenticates them with a value derived from an empty secret that anyone can compute, allowing unauthenticated attackers to mark arbitrary WooCommerce orders as paid and completed.
