CVE-2026-76207: Missing Critical Step in Authentication in thorsten phpMyFAQ
Description
phpMyFAQ versions prior to 4.1.7 have a vulnerability in the two-factor authentication process where remember-me tokens are issued before the second-factor verification completes. This allows attackers with valid credentials to bypass 2FA by replaying the remember-me cookie, gaining full authenticated access without completing the second-factor challenge.

Technical Analysis
CVE-2026-76207 describes a two-factor authentication bypass in phpMyFAQ before version 4.1.7. The vulnerability arises because remember-me tokens are issued before the completion of 2FA verification. An attacker who has valid user credentials can obtain a remember-me cookie, skip the 2FA step, and reuse the cookie to authenticate fully without the second factor.
Potential Impact
An attacker with valid credentials can bypass the second-factor authentication mechanism, potentially gaining unauthorized access to user accounts protected by 2FA. This undermines the security benefits of two-factor authentication and increases the risk of account compromise.
Mitigation Recommendations
Upgrade phpMyFAQ to version 4.1.7 or later, where this vulnerability has been fixed. No other mitigation guidance is provided, so applying the official patch is the recommended action.
