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.","state":0,"publishedAt":"2026-10-09T15:22:10.562+00:00","modifiedAt":"2026-10-09T16:45:22.243+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:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-33rr-wq23-g6gg","https://github.com/0xJacky/nginx-ui/commit/a3999bd78a3b97ab22e6b5e9fd478ac57598a954","https://github.com/0xJacky/nginx-ui/releases/tag/v2.5.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107809","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107809","identifiers":["CVE-2026-107809"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
