Unauthenticated administrator creation via unchecked role
Published Mar 3, 2026 · Updated Mar 3, 2026
Improper privilege management in WPEverest User Registration & Membership 5.1.2 and earlier allows remote attackers to create administrator accounts. The membership-registration handler accepts a client-supplied role and assigns it without enforcing a server-side allowlist. No authentication or user interaction is required; a forged administrator account grants control over the WordPress site and its data.
