Prior to 2.4.1, the POST /api/users/:id user-management endpoint permits an authenticated user to change another user's password without passing RequireSecureSession, even though the self-service password-change path requires that step-up. An attacker with an authenticated account can change the initial administrator's password, invalidate existing administrator tokens, and then authenticate as the administrator. This issue is fixed in version 2.4.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-285","CWE-862"],"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-2gc7-j998-5xx6","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-2gc7-j998-5xx6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-84314","score":0.00419,"percentile":0.35936,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-2gc7-j998-5xx6","url":"https://osv.dev/vulnerability/GHSA-2gc7-j998-5xx6","summary":"Nginx UI: Account Takeover via Missing `RequireSecureSession` on User Management Endpoint","modified":"2026-10-19T21:41:14.823819947Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":["<1.9.10-0.20260703131214-23d1934099b0"],"fixed":["1.9.10-0.20260703131214-23d1934099b0"]}]},{"id":"GO-2026-6771","url":"https://osv.dev/vulnerability/GO-2026-6771","summary":"Nginx UI: Account Takeover via Missing `RequireSecureSession` on User Management Endpoint in github.com/0xJacky/Nginx-UI","modified":"2026-10-19T21:31:37.803275458Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":["<1.9.10-0.20260703131214-23d1934099b0"],"fixed":["1.9.10-0.20260703131214-23d1934099b0"]}]}],"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).
