Description
The UniPAY Payment Gateway For WooCommerce WordPress plugin up to version 2.3 contains an authentication flaw where payment notifications are not properly verified. The signature verification uses a merchant secret that is empty by default, enabling unauthenticated attackers to forge payment notifications and mark arbitrary orders as paid.
