Administrator account creation via attacker-chosen registration role
Published Dec 31, 2024 · Updated Apr 28, 2026
Privilege escalation in VibeThemes VibeBP 1.9.9.4.1 and earlier allows remote attackers to register Administrator accounts. The vibebp_register_user AJAX handler copies an attacker-controlled default_role setting into user_args and passes it to wp_insert_user without restricting allowed roles. No authentication is required, but the public registration flow and its signup nonce must be reachable; exploitation grants full WordPress site administration.
