Versions 3.2.0 through 4.1.5 contain an authentication bypass in its public two-factor authentication verification flow: an unauthenticated attacker can submit an account’s numeric user ID and a valid or brute-forced six-digit TOTP code without first authenticating with the account password, allowing takeover of any 2FA-enabled account, including administrator accounts. Version 4.1.6 is patched by binding TOTP verification to a session established after successful password authentication and limiting failed TOTP attempts. No official workaround is documented; affected installations should upgrade to 4.1.6 or later.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-56737)\n\nAffected packages:\n\n- `thorsten/phpmyfaq >= 3.2.0, < 4.1.6`\n- `phpmyfaq/phpmyfaq >= 3.2.0, < 4.1.6`\n\nPatched in:\n\n- `thorsten/phpmyfaq 4.1.6`\n- `phpmyfaq/phpmyfaq 4.1.6`\n\nSource: https://github.com/advisories/GHSA-8gpw-xvpf-hvx5","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":44.6,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
