An issue exists in the CardGate Payments plugin up to and including 3.1.15 for WooCommerce. Lack of origin authentication in the IPN callback processing function in cardgate/cardgate.php allows an malicious user to remotely replace critical plugin settings (merchant ID, secret key, etc.) and therefore bypass the payment process (e.g., spoof an order status by manually sending an IPN callback request with a valid signature but without real payment) and/or receive all of the subsequent payments.
