CVE-2026-76207Network attack vector

Authenticated 2FA bypass via premature persistent token

Published Aug 19, 2026 · Updated Aug 25, 2026

Authentication bypass in phpMyFAQ before 4.1.7 allows remote authenticated users to access 2FA-protected accounts without a second factor. The login routine issues a persistent authentication token after password validation but before 2FA completes, and the cookie lookup accepts that token without checking 2FA status. Valid primary credentials and persistent-login selection are required; replaying the cookie grants the account's full authenticated access.
