CVE-2026-3594

What is known

The Riaxe Product Customizer plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.4 via the '/wp-json/InkXEProductDesignerLite/orders' REST API endpoint. The endpoint is registered with 'permission_callback' set to '__return_true', meaning no authentication or authorization checks are performed. The endpoint queries WooCommerce order data from the database and returns it to the requester, including customer first and last names, customer IDs, order IDs, order totals, order dates, currencies, and order statuses. This makes it possible for unauthenticated attackers to extract sensitive customer and order information from the WooCommerce store.

Business impact

Successful exploitation of CVE-2026-3594, a medium vulnerability (CVSS 5.3) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
