This makes it possible for unauthenticated attackers to elevate their privileges to Administrator by supplying a user_roles=administrator parameter when creating an account during checkout, resulting in full site takeover.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":9.8,"severity":"critical","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1794050790206,"publishedAt":1794050790206,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/714d10b0-526c-4347-a369-85fc32ef3478?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/registration-form-for-woocommerce/tags/1.1.3/includes/FormHandler.php#L354"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/registration-form-for-woocommerce/tags/1.1.3/includes/FormHandler.php#L407"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/changeset?old_path=%2Fregistration-form-for-woocommerce%2Ftags%2F1.1.4&new_path=%2Fregistration-form-for-woocommerce%2Ftags%2F1.1.5"}],"remediation":[],"revision":"6cea21a597f7ce97c13b938d94063bc9ce86ad7a99d623d9a7c454144bcf6d68","sources":[{"modifiedAt":1794050790206,"name":"CNA: Wordfence","retrievedAt":1794053390023,"url":"https://www.cve.org/CVERecord?id=CVE-2026-119075"}],"ssvc":null,"status":"published","title":"Registration Form for WooCommerce <= 1.1.4 - Unauthenticated Privilege Escalation to 'user_roles' Parameter at Checkout","updatedAt":1794053390023}
