CVE-2026-76213
HighCVSS 7.4Summary
phpMyFAQ before 4.1.7 contains a brute-force vulnerability in the two-factor authentication step where the failure counter is session-scoped and reset on each successful password re-authentication. Attackers with a valid password can bypass the five-attempt limit by obtaining a fresh session cookie and repeatedly re-authenticating to reset the counter, enabling unbounded TOTP code guessing.
Risk Assessment
Risk of two-factor authentication bypass and account takeover, potentially leading to unauthorized data access.
Recommendation
Update phpMyFAQ to version 4.1.7 or later. Implement additional rate-limiting mechanisms such as IP blocking or a global failure counter.
