AI-suggested

Users should manually configure the merchant secret to enable proper verification of payment notifications.

Description

The Payment Integration Wompi WordPress plugin up to version 4.0.1 fails to verify the authenticity of incoming payment notifications by default. This occurs because the callback's checksum relies on a merchant secret that is empty until manually configured. As a result, an unauthenticated attacker can forge payment notifications and mark arbitrary orders as paid.
