Brute Force Bypass in miniOrange 2FA WordPress Plugin

Executive Summary

The miniOrange 2FA WordPress plugin before version 6.2.8 has a flaw where it does not properly restrict the number of attempts for second-factor verification. Instead of tracking attempts per user account, it uses a client-supplied identifier that changes with each login. This allows an attacker who already knows a user's password to repeatedly guess the one-time code without being locked out, potentially gaining unauthorized access to the account.
