From 2.0.0 until 2.5.0, POST /api/login checks EnabledOTP but does not require a WebAuthn assertion when EnabledPasskey is true and no TOTP secret is configured. A passkey-only account is therefore issued a session after password verification, despite Enabled2FA reporting that the account has a second factor. An attacker who obtains the password can take over the account and reach administrative functionality without the registered passkey. This issue is fixed in version 2.5.0.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-287","CWE-305","CWE-308"],"references":["https://github.com/0xJacky/nginx-ui/commit/95cd21b70814e5d9a48a359aa238aeea1ac97429","https://github.com/0xJacky/nginx-ui/releases/tag/v2.5.0","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-45gv-9wjv-xh7p","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-45gv-9wjv-xh7p"],"products":["nginxui:nginx_ui"],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-107808","score":0.00413,"percentile":0.35265,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-45gv-9wjv-xh7p","url":"https://osv.dev/vulnerability/GHSA-45gv-9wjv-xh7p","summary":"Nginx UI: Authentication bypass: password login does not enforce a passkey-only second factor (2FA bypass)","modified":"2026-10-19T21:41:12.332793483Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":[">=1.9.10-0.20250517140552-daee3ac7ade1 <1.9.10-0.20260728074558-95cd21b70814"],"fixed":["1.9.10-0.20260728074558-95cd21b70814"]}]},{"id":"GO-2026-6704","url":"https://osv.dev/vulnerability/GO-2026-6704","summary":"Nginx UI: Authentication bypass: password login does not enforce a passkey-only second factor (2FA bypass) in github.com/0xJacky/Nginx-UI","modified":"2026-10-19T21:31:49.017741285Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":[">=1.9.10-0.20250517140552-daee3ac7ade1 <1.9.10-0.20260728074558-95cd21b70814"],"fixed":["1.9.10-0.20260728074558-95cd21b70814"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
