Super Payments <= 1.43.0 - Payment Verification Bypass to Unauthenticated Arbitrary Order Payment Forgery
The Super Payments plugin for WordPress is vulnerable to Payment Verification Bypass in all versions up to, and including, 1.43.0. This is due to missing rejection of an empty signing key in the webhook signature verification logic, allowing anyone to compute a valid HMAC with an empty secret. This makes it possible for unauthenticated attackers to mark arbitrary WooCommerce orders as paid without making a payment, by forging a valid webhook signature using an empty signing key.
