CWE-345 · CNA: WPScan · CVSS v3.1 · 1 reference · NVD status: Deferred

Description

The Visma Pay for WooCommerce WordPress plugin before 1.2.2 does not verify the authenticity of payment gateway return requests, relying on a merchant secret that is empty on a store which has not entered its credentials, allowing unauthenticated attackers to mark arbitrary orders as paid and to disclose the name, email address and postal address of any order's customer.
