CVE-2023-4948Network attack vector

Order data modification via unchecked AJAX action

Published Sep 14, 2023 · Updated Apr 8, 2026

Missing authorization in Yan&Co WooCommerce CVR Payment Gateway before 6.1.0 allows remote authenticated users to alter order CVR numbers. The refresh_order_cvr_data AJAX action updates an order's CVR value without checking the caller's WordPress capability. A contributor-level account or higher is required, and exploitation changes order data rather than disclosing it or interrupting service.
