Payex Payment Gateway for WooCommerce <= 1.2.10 - Unauthenticated Payment Confirmation Forgery via Empty-Default Secret Key

Description

The plugin does not properly verify the authenticity of incoming payment notifications, relying on a validation secret that is empty by default, allowing unauthenticated attackers to forge a valid payment confirmation and mark any order as paid.
