{"id":"CVE-2026-119075","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-119075","summary":"The Registration Form for WooCommerce plugin for WordPress is vulnerable to privilege escalation due to a missing allow-list check in the FormHandler::validate_checkout_fields() function…","details":"The Registration Form for WooCommerce plugin for WordPress is vulnerable to privilege escalation due to a missing allow-list check in the FormHandler::validate_checkout_fields() function in versions up to, and including, 1.1.4 The My Account registration path (validate_fields()) validates a submitted 'tgwcfb/user-roles' value against the form's configured allowed roles, but the checkout registration path (validate_checkout_fields(), hooked to woocommerce_after_checkout_validation) stores the raw $_POST['user_roles'] value in $this->valid_data without any allow-list enforcement, and add_user_data() then injects that value into woocommerce_new_customer_data as the new account's role. 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.","published":"2026-11-07T12:17:44.033","modified":"2026-11-07T12:17:44.157","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/registration-form-for-woocommerce/tags/1.1.3/includes/FormHandler.php#L354"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/registration-form-for-woocommerce/tags/1.1.3/includes/FormHandler.php#L407"},{"type":"WEB","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"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/714d10b0-526c-4347-a369-85fc32ef3478?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-07T12:17:44.157"}}
