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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-706","CWE-50","CWE-200"],"references":["https://github.com/vitejs/vite/commit/813ddd6155c3d54801e264ba832d8347f6f66b32","https://github.com/vitejs/vite/pull/13348","https://github.com/vitejs/vite/security/advisories/GHSA-353f-5xf4-qw67","https://github.com/vitejs/vite/commit/813ddd6155c3d54801e264ba832d8347f6f66b32","https://github.com/vitejs/vite/pull/13348"],"products":["vitejs:vite"],"source":"nvd","synced_at":"2026-10-19T21:38:24.161619714+00:00"},"epss":{"cve":"CVE-2023-34092","score":0.03152,"percentile":0.87952,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-353f-5xf4-qw67","url":"https://osv.dev/vulnerability/GHSA-353f-5xf4-qw67","summary":"Vite Server Options (server.fs.deny) can be bypassed using double forward-slash (//)","modified":"2026-09-10T03:50:01.912023705Z","packages":[{"ecosystem":"npm","name":"vite","purl":"pkg:npm/vite","ranges":["<2.9.16"],"fixed":["2.9.16"]},{"ecosystem":"npm","name":"vite","purl":"pkg:npm/vite","ranges":[">=3.0.2 <3.2.7"],"fixed":["3.2.7"]},{"ecosystem":"npm","name":"vite","purl":"pkg:npm/vite","ranges":[">=4.0.0 <4.0.5"],"fixed":["4.0.5"]},{"ecosystem":"npm","name":"vite","purl":"pkg:npm/vite","ranges":[">=4.1.0 <4.1.5"],"fixed":["4.1.5"]},{"ecosystem":"npm","name":"vite","purl":"pkg:npm/vite","ranges":[">=4.2.0 <4.2.3"],"fixed":["4.2.3"]},{"ecosystem":"npm","name":"vite","purl":"pkg:npm/vite","ranges":[">=4.3.0 <4.3.9"],"fixed":["4.3.9"]}]}],"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).
