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":"2026-10-09T16:17:25.387+00:00","modifiedAt":"2026-10-20T15:15:58.807+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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/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"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-107809","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-352"],"productCriteria":["cpe:2.3:a:nginxui:nginx_ui:*:*:*:*:*:*:*:*"],"sourceDates":{"published":"2026-10-09T16:17:25.387","lastModified":"2026-10-20T15:15:58.807"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
