Prior to version 2.3.4, the nginx-ui configuration improperly handles URL-encoded traversal sequences. When specially crafted paths are supplied, the backend resolves them to the base Nginx configuration directory and executes the operation on the base directory (/etc/nginx). In particular, this allows an authenticated user to remove the entire /etc/nginx directory, resulting in a partial Denial of Service. This issue has been patched in version 2.3.4.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-22","CWE-73"],"references":["https://github.com/0xJacky/nginx-ui/releases/tag/v2.3.4","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-m8p8-53vf-8357","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-m8p8-53vf-8357"],"products":["nginxui:nginx_ui"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-33027","score":0.00413,"percentile":0.35594,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m8p8-53vf-8357","url":"https://osv.dev/vulnerability/GHSA-m8p8-53vf-8357","summary":"Nginx Configuration Directory Vulnerable to Recursive Deletion via Improper Path Validation","modified":"2026-09-10T03:51:00.546251070Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":["<=1.99"],"fixed":[]}]},{"id":"GO-2026-4907","url":"https://osv.dev/vulnerability/GO-2026-4907","summary":"Nginx Configuration Directory Vulnerable to Recursive Deletion via Improper Path Validation in github.com/0xJacky/Nginx-UI","modified":"2026-04-02T21:20:06.086493Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":["all versions"],"fixed":[]}]}],"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).
