{"cve":"CVE-2026-4140","nvd":{"published":"2026-04-22T09:16:24.857","modified":"2026-06-17T10:56:03.120","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-352"],"references":["https://plugins.trac.wordpress.org/browser/ni-woocommerce-order-export/tags/3.1.6/include/ni-order-export.php#L136","https://plugins.trac.wordpress.org/browser/ni-woocommerce-order-export/tags/3.1.6/include/ni-order-setting.php#L59","https://plugins.trac.wordpress.org/browser/ni-woocommerce-order-export/trunk/include/ni-order-export.php#L136","https://plugins.trac.wordpress.org/browser/ni-woocommerce-order-export/trunk/include/ni-order-setting.php#L59","https://www.wordfence.com/threat-intel/vulnerabilities/id/2d62c49c-3a33-4865-abcc-22d8e38ac198?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-4140","score":0.00156,"percentile":0.04743,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
