CVE-2026-15255Public exploitNetwork attack vector

Unauthenticated submission disclosure via mismatched OTP identity

Published Jul 30, 2026 · Updated Jul 30, 2026

IDOR in Metagauss RegistrationMagic before 6.0.9.4 allows remote attackers to read other users' front-end form submissions. The front-end submissions flow validates rm_secure_otp against one front-user record but uses the attacker-controlled rm_autorized_email cookie to select another identity. Exploitation requires the non-default front-end OTP submissions configuration, an attacker-owned OTP, and the victim's email address; exposed records can contain personal information.
