Summary
Vite is a frontend tooling framework for JavaScript that, prior to versions 8.0.16, 7.3.5, and 6.4.3, could return the contents of files specified by server.fs.deny to the browser on Windows. Issues with NTFS ADS path normalization allowed unauthorized access to sensitive files.
Risk Assessment
Organizations may be exposed to the disclosure of sensitive data, such as configuration files, which could lead to serious security incidents.
Recommendation
It is recommended to update Vite to versions 8.0.16, 7.3.5, or 6.4.3 to mitigate this vulnerability.
Other vulnerabilities in Vite
See all- CVE-2026-39365Medium
Vite, a frontend tooling framework for JavaScript, versions 6.0.0 to before 6.4.2, 7.3.2, and 8.0.5, has a vulnerability in handling .map requests for optimized dependencies. The dev server resolves file paths and calls readFile without restricting ../ segments in the URL, allowing bypass of the server.fs.strict allow list and retrieval of .map files outside the project root if they can be parsed as valid source map JSON.
- CVE-2026-39364High
Vite versions 7.1.0 to before 7.3.2 and 8.0.5 allow bypassing server.fs.deny restrictions. Files like .env or *.crt can be retrieved with HTTP 200 by appending query parameters ?raw, ?import&raw, or ?import&url&inline.
- CVE-2026-39363High
A vulnerability in Vite (a frontend tooling framework for JavaScript) from 6.0.0 to before 6.4.2, 7.3.2, and 8.0.5 allows an attacker who can connect to the Vite dev server's WebSocket without an Origin header to invoke fetchModule via the vite:invoke event and read arbitrary files on the server as a JavaScript string. HTTP access controls are not applied to this WebSocket channel.
- CVE-2023-34092High
Vite, a frontend tooling, has a vulnerability that allows bypassing server options (`server.fs.deny`) using double forward-slash (//). This enables unauthenticated users to read files from the Vite application's root path, including default `fs.deny` settings.
Original NVD description (English source)
Vite is a frontend tooling framework for JavaScript. Prior to 8.0.16, 7.3.5, and 6.4.3, the contents of files that are specified by server.fs.deny can be returned to the browser on Windows. Vite’s dev server denies direct access to sensitive files through server.fs.deny, including entries such as .env, .env.*, and *.{crt,pem}. However, on Windows, the deny logic does not correctly normalize NTFS ADS path forms before access checks are applied. Because of this, requests such as /.env::$DATA?raw are treated as allowed paths, while Windows resolves them to the original file's default data stream. Similar to that, Windows allows accessing a file using a different name with the 8.3 short name compatibility feature. Vite did not reject accessing files via them. This vulnerability is fixed in 8.0.16, 7.3.5, and 6.4.3.
