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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"0xJacky","product":"nginx-ui","versions":[{"version":">= 2.0.0, < 2.5.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":8.1,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.2,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-09T17:16:59.141852Z","id":"CVE-2026-107808","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-287"},{"lang":"en","value":"CWE-305"},{"lang":"en","value":"CWE-308"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:nginxui:nginx_ui:*:*:*:*:*:*:*:*","versionStartIncluding":"2.0.0","versionEndExcluding":"2.5.0","matchCriteriaId":"0C45DE3B-CE6E-4A52-93DA-8B247A56835D"}]}]}],"references":[{"url":"https://github.com/0xJacky/nginx-ui/commit/95cd21b70814e5d9a48a359aa238aeea1ac97429","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/0xJacky/nginx-ui/releases/tag/v2.5.0","source":"security-advisories@github.com","tags":["Release Notes"]},{"url":"https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-45gv-9wjv-xh7p","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory","Mitigation"]},{"url":"https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-45gv-9wjv-xh7p","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Vendor Advisory","Mitigation"]}]}
