## Overview

phpMyFAQ 3.2.0 before 4.1.9 and 4.2.0-alpha before 4.2.0-beta contains an insecure direct object reference vulnerability in GET /admin/api/user/data/{userId}, which returns any user's full faquserdata row, including the live TOTP secret, without a SuperAdmin or protected-target check. Delegated administrators with user-management rights can read a SuperAdmin's TOTP secret and generate valid codes to bypass two-factor authentication.

## Affected

- `phpMyFAQ >= 3.2.0 < 4.1.9`
- `phpMyFAQ >= 4.2.0-alpha < 4.2.0-beta`
