{"id":"CVE-2023-34092","aliases":["GHSA-353f-5xf4-qw67"],"url":"https://o3.security/vulnerability/CVE-2023-34092","summary":"Vite Server Options (server.fs.deny) can be bypassed using double forward-slash (//)","details":"Vite provides frontend tooling. Prior to versions 2.9.16, 3.2.7, 4.0.5, 4.1.5, 4.2.3, and 4.3.9, Vite Server Options (`server.fs.deny`) can be bypassed using double forward-slash (//) allows any unauthenticated user to read file from the Vite root-path of the application including the default `fs.deny` settings (`['.env', '.env.*', '*.{crt,pem}']`). Only users explicitly exposing the Vite dev server to the network (using `--host` or `server.host` config option) are affected, and only files in the immediate Vite project root folder could be exposed. This issue is fixed in vite@4.3.9, vite@4.2.3, vite@4.1.5, vite@4.0.5, vite@3.2.7, and vite@2.9.16.","published":"2023-06-01T16:29:51.428Z","modified":"2026-08-08T03:47:40.428826792Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"npm","name":"vite","fixedVersion":"2.9.16"},{"ecosystem":"npm","name":"vite","fixedVersion":"3.2.7"},{"ecosystem":"npm","name":"vite","fixedVersion":"4.0.5"},{"ecosystem":"npm","name":"vite","fixedVersion":"4.1.5"},{"ecosystem":"npm","name":"vite","fixedVersion":"4.2.3"},{"ecosystem":"npm","name":"vite","fixedVersion":"4.3.9"}],"fix":{"url":"https://github.com/vitejs/vite/commit/813ddd6155c3d54801e264ba832d8347f6f66b32","label":"vitejs/vite@813ddd6"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/34xxx/CVE-2023-34092.json"},{"type":"ADVISORY","url":"https://github.com/vitejs/vite/security/advisories/GHSA-353f-5xf4-qw67"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-34092"},{"type":"FIX","url":"https://github.com/vitejs/vite/commit/813ddd6155c3d54801e264ba832d8347f6f66b32"},{"type":"FIX","url":"https://github.com/vitejs/vite/pull/13348"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-08T03:47:40.428826792Z"}}
