CVE-2025-31125
MediumCVSS 5.3KEVSummary
Vite is a frontend tooling framework for javascript. Vite exposes content of non-allowed files using ?inline&import or ?raw?import. Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected. This vulnerability is fixed in 6.2.4, 6.1.3, 6.0.13, 5.4.16, and 4.5.11.
Risk Assessment
Exposure of non-allowed file content can lead to leakage of source code, configuration, or sensitive data from the development server.
Recommendation
Update Vite to version 6.2.4, 6.1.3, 6.0.13, 5.4.16, or 4.5.11 (or later) and avoid exposing the development server to the network.
Other vulnerabilities in Vite
See all- CVE-2026-53571High
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.
- 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.
