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.","state":0,"publishedAt":"2026-10-09T15:11:44.387+00:00","modifiedAt":"2026-10-09T17:19:53.438+00:00","affected":[{"ecosystem":"Vendor product","name":"nginx-ui","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"0xJacky\",\n                    \"product\": \"nginx-ui\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.0.0, < 2.5.0\",\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/0xJacky/nginx-ui/security/advisories/GHSA-45gv-9wjv-xh7p","https://github.com/0xJacky/nginx-ui/commit/95cd21b70814e5d9a48a359aa238aeea1ac97429","https://github.com/0xJacky/nginx-ui/releases/tag/v2.5.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107808","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107808","identifiers":["CVE-2026-107808"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
