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.","state":0,"publishedAt":"2026-09-24T14:59:35.695+00:00","modifiedAt":"2026-09-29T02:47:34.341+00:00","affected":[{"ecosystem":"Vendor product","name":"phpMyFAQ","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"thorsten\",\n                    \"product\": \"phpMyFAQ\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 3.2.0, < 4.1.6\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.1,"severity":"HIGH"}],"references":["https://github.com/thorsten/phpMyFAQ/security/advisories/GHSA-8gpw-xvpf-hvx5","https://github.com/thorsten/phpMyFAQ/commit/410208b90f1d01534812ac5203d3e8d9c7bd591f","https://github.com/thorsten/phpMyFAQ/commit/5097dff341fb01e93e8561e7261b3ae657df715a","https://github.com/thorsten/phpMyFAQ/commit/6a69f6e2142fde722165c65b7e0a49f3176e87be"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-56737","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-56737","identifiers":["CVE-2026-56737"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
