From 2.2.0 until 2.6.0, the bundled reverse proxy does not preserve the external client identity used by Gin because the backend has no trusted proxy configuration. Management requests can be attributed to loopback and pass the IP allowlist loopback exception, although valid credentials are still required. Failed logins from different external clients are also attributed to the same loopback address, allowing an unauthenticated attacker to trigger a shared temporary login ban for password or OTP authentication without invalidating existing sessions. This issue is fixed in version 2.6.0.","state":0,"publishedAt":"2026-10-09T15:17:09.75+00:00","modifiedAt":"2026-10-09T16:38:57.82+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/0xJacky/nginx-ui/commit/e30e331303fc21cf077a2bea724bd79e66892eaf","https://github.com/0xJacky/nginx-ui/releases/tag/v2.6.0","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-9h23-53f4-q947"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-107804","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-346"],"productCriteria":[],"sourceDates":{"published":"2026-10-09T15:17:09.750","lastModified":"2026-10-09T16:38:57.820"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
