At a glance
CVE-2026-4140 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Ni WooCommerce Order Export WordPress plugin, affecting versions <= 3.1.6. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed April 2026, reported by afnaan.
Vulnerability Overview
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.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-352: Cross-Site Request Forgery (CSRF)
Ni WooCommerce Order Export <= 3.1.6 carries this weakness at page, and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. No fixed build of this plugin is recorded for Ni WooCommerce Order Export yet, so installs running <= 3.1.6 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
The attempt arrives as an ordinary request to Ni WooCommerce Order Export: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
