Administrator account creation via unchecked role parameter

Published Oct 11, 2025 · Updated Apr 8, 2026

Privilege escalation in the WP Freeio plugin 1.2.21 and earlier allows remote attackers to create WordPress administrator accounts. WP_Freeio_User::process_register() copies the submitted role into user data without restricting it before calling wp_insert_user(). Public registration must be reachable; successful exploitation grants administrative control over site content, plugins, themes, and settings.
