CVE-2026-119075

CriticalCVSS 9.8
Published: Updated: Translated: NVD NIST

Summary

The Registration Form for WooCommerce plugin for WordPress is vulnerable to privilege escalation due to a missing allow-list check in FormHandler::validate_checkout_fields() in versions up to and including 1.1.4. The checkout registration path stores the raw $_POST['user_roles'] value without validation, and add_user_data() injects it as the new account's role.

Risk Assessment

Unauthenticated attackers can create an account with the Administrator role, resulting in full site takeover.

Recommendation

Update the plugin to a version later than 1.1.4 and verify that no unauthorized administrator accounts were created.

Original NVD description (English source)

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.
