Account takeover via attacker-controlled TOTP secret
Published Jul 31, 2026 · Updated Jul 31, 2026
Authentication bypass in miniOrange 2FA before 6.2.6 allows remote attackers with a victim's password to access the victim's WordPress account. The mo2f_validate_otp_for_configuration AJAX action verifies the submitted OTP against the request's ga_secret and overwrites the victim's stored mo2f_gauth_key. No prior WordPress session is required, but the victim's password and live challenge values are; success yields the victim's authenticated session, including administrator access.
