CVE-2026-111905 Details
Description
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.
A vulnerability exists in phpMyFAQ versions 3.2.0 prior to 4.1.9 and 4.2.0-alpha prior to 4.2.0-beta, allowing insecure direct object reference (IDOR) through the admin API user data endpoint. This vulnerability enables delegated administrators with user-management rights to access any user's full data, including sensitive information such as the TOTP secret, without proper authorization checks. As a result, an attacker could bypass two-factor authentication, particularly for SuperAdmin accounts.
Users can upgrade to phpMyFAQ version 4.1.9 or later to address this vulnerability.
