{"id":"CVE-2026-107808","summary":"Nginx UI: Authentication bypass: password login does not enforce a passkey-only second factor (2FA bypass)","details":"Nginx UI is a web user interface for the Nginx web server. 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.","aliases":["GHSA-45gv-9wjv-xh7p"],"modified":"2026-10-10T02:47:31.486630409Z","published":"2026-10-09T15:11:44.387Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-287","CWE-305","CWE-308"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107808.json"},"references":[{"type":"FIX","url":"https://github.com/0xJacky/nginx-ui/commit/95cd21b70814e5d9a48a359aa238aeea1ac97429"},{"type":"WEB","url":"https://github.com/0xJacky/nginx-ui/releases/tag/v2.5.0"},{"type":"ADVISORY","url":"https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-45gv-9wjv-xh7p"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/107xxx/CVE-2026-107808.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-107808"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/0xjacky/nginx-ui","events":[{"introduced":"daee3ac7ade1162805b3af07807e2f4dc2affaf5"},{"fixed":"acb59fdd81dbdd60abd0004e9ade573186a3be43"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"2.0.0"},{"fixed":"2.5.0"}]}}],"versions":["v2.4.3","v2.4.2","v2.4.1","v2.4.0","v2.3.11","v2.3.10","v2.3.9","v2.3.8","v2.3.7","v2.3.6","v2.3.5","v2.3.4","v2.3.3","v2.3.2","v2.3.1","v2.3.0","v2.2.1","v2.2.0-patch.1","v2.2.0","v2.1.17","v2.1.16","v2.1.15","v2.1.14","v2.1.13","v2.1.12","v2.1.11","v2.1.10","v2.1.9","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4-patch.1","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0-patch.1","v2.1.0","v2.1.0-rc.3","v2.1.0-rc.2","v2.1.0-rc.1","v2.1.0-beta.1","v2.0.2","v2.0.1","v2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-107808.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
