{"cve":"CVE-2026-107809","nvd":{"published":"2026-10-09T16:17:25.387","modified":"2026-10-20T15:15:58.807","status":"Analyzed","description":"Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, AuthRequired accepts a browser-managed token cookie as an API credential after the front end stores the JWT in that cookie. Because management endpoints do not universally require a CSRF token or perform Origin or Referer validation, a remote attacker can induce a logged-in administrator's browser to submit authenticated cross-site state-changing requests, including POST /api/configs. The attack requires an administrator account without OTP/Passkey or a target endpoint that does not require secure-session proof. The attacker cannot read the cross-origin response but can modify Nginx configuration, trigger reloads, or invoke other management operations reachable with the victim's session. This issue is fixed in version 2.5.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-352"],"references":["https://github.com/0xJacky/nginx-ui/commit/a3999bd78a3b97ab22e6b5e9fd478ac57598a954","https://github.com/0xJacky/nginx-ui/releases/tag/v2.5.0","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-33rr-wq23-g6gg"],"products":["nginxui:nginx_ui"],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-107809","score":0.00226,"percentile":0.13243,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-33rr-wq23-g6gg","url":"https://osv.dev/vulnerability/GHSA-33rr-wq23-g6gg","summary":"Nginx-UI AuthRequired token cookie fallback enables CSRF against management APIs","modified":"2026-10-19T21:41:07.284327902Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":[">=1.9.10-0.20250517140552-daee3ac7ade1 <1.9.10-0.20260728074433-a3999bd78a3b"],"fixed":["1.9.10-0.20260728074433-a3999bd78a3b"]}]},{"id":"GO-2026-6703","url":"https://osv.dev/vulnerability/GO-2026-6703","summary":"Nginx-UI AuthRequired token cookie fallback enables CSRF against management APIs in github.com/0xJacky/Nginx-UI","modified":"2026-10-19T21:31:52.274284585Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":[">=1.9.10-0.20250517140552-daee3ac7ade1 <1.9.10-0.20260728074433-a3999bd78a3b"],"fixed":["1.9.10-0.20260728074433-a3999bd78a3b"]}]}],"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).
