Published Jan 17, 2026CWE-862EPSS 0.35%

Overview

CVE-2025-14463 is a medium-severity vulnerability. It was published on January 17, 2026 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The Payment Button for PayPal plugin for WordPress is vulnerable to unauthorized order creation in all versions up to, and including, 1.2.3.41. This is due to the plugin exposing a public AJAX endpoint (`wppaypalcheckout_ajax_process_order`) that processes checkout results without any authentication or server-side verification of the PayPal transaction. This makes it possible for unauthenticated attackers to create arbitrary orders on the site with any chosen transaction ID, payment status, product name, amount, or customer information via direct POST requests to the AJAX endpoint, granted they can bypass basic parameter validation. If email sending is enabled, the plugin will also trigger purchase receipt emails to any email address supplied in the request, leading to order database corruption and unauthorized outgoing emails without any real PayPal transaction taking place.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
