Administrator escalation via unchecked capability metadata
Published Jan 28, 2026 · Updated Jan 28, 2026
Privilege escalation in N-Media MemberHero – Simple User Registration & Login 6.7 and earlier allows remote authenticated users to become administrators. The profile_save_field AJAX handler passes submitted profile data to WPR_User::save(), which writes wp_capabilities as user meta without filtering capability keys. Subscriber access is sufficient to submit a crafted profile update and gain full WordPress administrator control.
