Summary

The Visma Pay for WooCommerce WordPress plugin before 1.2.2 does not verify the authenticity of payment gateway return requests (CWE-345). The check relies on a merchant secret that is empty on stores that have not entered their credentials, so an unauthenticated remote attacker can mark arbitrary orders as paid and read the name, email address and postal address of order customers. A public exploit is linked in the references.
