CVE-2025-14461

What is known

The Xendit Payment plugin for WordPress is vulnerable to unauthorized order status manipulation in all versions up to, and including, 6.0.2. This is due to the plugin exposing a publicly accessible WooCommerce API callback endpoint (`wc_xendit_callback`) that processes payment callbacks without any authentication or cryptographic verification that the requests originate from Xendit's payment gateway. This makes it possible for unauthenticated attackers to mark any WooCommerce order as paid by sending a crafted POST request to the callback URL with a JSON body containing an `external_id` matching the order ID pattern and a `status` of 'PAID' or 'SETTLED', granted they can enumerate order IDs (which are sequential integers). This leads to orders being fraudulently marked as completed without any actual payment, resulting in financial loss and inventory depletion.

Business impact

Successful exploitation of CVE-2025-14461, 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.
