Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, POST /api/otp_enroll and POST /api/finish_passkey_register are registered outside RequireSecureSession and accept a normal authenticated session without verifying the current password. An attacker with a stolen JWT can bind an attacker-controlled TOTP secret when the victim has not already enabled TOTP, or can register an attacker-controlled passkey because that path has no equivalent existing-enrollment guard. These changes create persistent account access that can survive a password change and interfere with the legitimate user's authentication. This issue is fixed in version 2.4.1.
