Users should verify if a vendor advisory or update is available to address this issue. Until a fix is applied, avoid using affected versions or disable the UniPAY Payment Gateway plugin to prevent exploitation.

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.
