CVE-2026-76207: Missing Critical Step in Authentication in thorsten phpMyFAQ
phpMyFAQ versions before 4.1.7 have a vulnerability in their two-factor authentication process where remember-me tokens are issued before the second-factor verification completes. This allows attackers with valid credentials to bypass the 2FA challenge by obtaining and replaying the remember-me cookie, gaining full authenticated access without completing the second-factor step.
AI Analysis
Technical Summary
CVE-2026-76207 describes a two-factor authentication bypass vulnerability in phpMyFAQ prior to version 4.1.7. The issue arises because remember-me tokens are issued before the completion of the 2FA verification process. An attacker who already has valid user credentials can exploit this flaw by obtaining a remember-me cookie, which can then be replayed to bypass the 2FA challenge entirely, resulting in unauthorized full authentication.
Potential Impact
An attacker with valid credentials can bypass the second-factor authentication step, gaining full authenticated access to the phpMyFAQ system without completing 2FA. This undermines the security benefits of two-factor authentication and increases the risk of unauthorized access to sensitive information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid using vulnerable versions or disable the remember-me feature if possible to reduce risk.
