CVE-2024-7493Network attack vector

Unauthenticated administrator account creation via unrestricted registration data

Published Sep 6, 2024 · Updated Apr 8, 2026

Improper privilege management in WPCOM Member 1.5.2.1 and earlier allows remote attackers to register as site administrators. In form-validation.php, the registration path forwards attacker-controlled fields to wp_insert_user() without restricting the role value. Registration must be enabled and reachable, after which the resulting administrator account grants control over the WordPress site.
