Unauthenticated role escalation via tampered registration form
Published Sep 30, 2026 · Updated Sep 30, 2026
Privilege escalation in weDevs WP User Frontend 3.5.29 through 4.3.11 allows remote attackers to register with an Editor role. The frontend registration form accepts a tampered role value instead of enforcing the role configured for the form when PHP lacks the sodium extension. Exploitation requires a configured registration page and a PHP build without sodium; the resulting account gains Editor privileges.
