What fixes it

No source in this snapshot names a fixed version.

Description

The UniPAY Payment Gateway For WooCommerce WordPress plugin through 2.3 does not properly verify the authenticity of payment notifications, as their signature is checked against a merchant secret that is empty by default, allowing unauthenticated attackers to forge a valid notification and mark arbitrary orders as paid.
