Super Payments < 1.43.1 - Unauthenticated Payment Confirmation Forgery via Webhook Signature

Description

The Super Payments WordPress plugin before 1.43.1 does not properly verify the authenticity of incoming payment webhook notifications, as the signing key used to validate their signature is empty by default, allowing unauthenticated attackers to forge a valid signature and mark arbitrary WooCommerce orders as paid without payment.
