{"cve":"CVE-2026-84313","nvd":{"published":"2026-10-12T21:17:21.597","modified":"2026-10-15T14:17:29.597","status":"Deferred","description":"Nginx UI is a web user interface for the Nginx web server. Prior to 2.4.1, POST /api/otp_enroll and POST /api/finish_passkey_register are registered outside RequireSecureSession and accept a normal authenticated session without verifying the current password. An attacker with a stolen JWT can bind an attacker-controlled TOTP secret when the victim has not already enabled TOTP, or can register an attacker-controlled passkey because that path has no equivalent existing-enrollment guard. These changes create persistent account access that can survive a password change and interfere with the legitimate user's authentication. This issue is fixed in version 2.4.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-287","CWE-306"],"references":["https://github.com/0xJacky/nginx-ui/commit/23d1934099b05b2a01589b48129dc3d3159d91c2","https://github.com/0xJacky/nginx-ui/releases/tag/v2.4.1","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-gfrc-g87h-7h5w","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-gfrc-g87h-7h5w"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-84313","score":0.00542,"percentile":0.45306,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-gfrc-g87h-7h5w","url":"https://osv.dev/vulnerability/GHSA-gfrc-g87h-7h5w","summary":"Nginx UI: TOTP / passkey enrolment requires no re-authentication, enabling persistent account takeover","modified":"2026-10-19T21:40:57.843249117Z","packages":[{"ecosystem":"Go","name":"Nginx-UI","purl":"pkg:golang/Nginx-UI","ranges":["<1.9.10-0.20260703131214-23d1934099b0"],"fixed":["1.9.10-0.20260703131214-23d1934099b0"]}]},{"id":"GO-2026-6786","url":"https://osv.dev/vulnerability/GO-2026-6786","summary":"TOTP / passkey enrolment requires no re-authentication, enabling persistent account takeover in github.com/0xJacky/Nginx-UI","modified":"2026-10-19T21:31:50.624956898Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":["all versions"],"fixed":[]}]}],"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).
