Vite .map File Traversal (v6-<6.4.2, v7-<7.3.2, v8-<8.0.5)
CVE-2026-39365 - April 07, 2026

Vite is a frontend tooling framework for JavaScript. From 6.0.0 to before 6.4.2, 7.3.2, and 8.0.5, the dev servers handling of .map requests for optimized dependencies resolves file paths and calls readFile without restricting ../ segments in the URL. As a result, it is possible to bypass the server.fs.strict allow list and retrieve .map files located outside the project root, provided they can be parsed as valid source map JSON. This vulnerability is fixed in 6.4.2, 7.3.2, and 8.0.5.

Vite Dev Server File Retrieval via ?raw, Fixed in 7.3.2/8.0.5
CVE-2026-39364 - April 07, 2026

Vite is a frontend tooling framework for JavaScript. From 7.1.0 to before 7.3.2 and 8.0.5, on the Vite dev server, files that should be blocked by server.fs.deny (e.g., .env, *.crt) can be retrieved with HTTP 200 responses when query parameters such as ?raw, ?import&raw, or ?import&url&inline are appended. This vulnerability is fixed in 7.3.2 and 8.0.5.

Vite WebSocket RCE via vite:invoke pre6.4.2, pre7.3.2, pre8.0.5
CVE-2026-39363 - April 07, 2026

Vite is a frontend tooling framework for JavaScript. From 6.0.0 to before 6.4.2, 7.3.2, and 8.0.5, if it is possible to connect to the Vite dev servers WebSocket without an Origin header, an attacker can invoke fetchModule via the custom WebSocket event vite:invoke and combine file://... with ?raw (or ?inline) to retrieve the contents of arbitrary files on the server as a JavaScript string (e.g., export default "..."). The access control enforced in the HTTP request path (such as server.fs.allow) is not applied to this WebSocket-based execution path. This vulnerability is fixed in 6.4.2, 7.3.2, and 8.0.5.

Unauth File Read via /__vite_rsc_findSourceMapURL in @vitejs/plugin-rs pre-0.5.8
CVE-2025-68155 7.5 - High - December 16, 2025

@vitejs/plugin-rs provides React Server Components (RSC) support for Vite. Prior to version 0.5.8, the `/__vite_rsc_findSourceMapURL` endpoint in `@vitejs/plugin-rsc` allows unauthenticated arbitrary file read during development mode. An attacker can read any file accessible to the Node.js process by sending a crafted HTTP request with a `file://` URL in the `filename` query parameter. Version 0.5.8 fixes the issue.

Directory traversal

Vite dev server Windows URL deny-flaw (v2.9.18-7.1.11)
CVE-2025-62522 - October 20, 2025

Vite is a frontend tooling framework for JavaScript. In versions from 2.9.18 to before 3.0.0, 3.2.9 to before 4.0.0, 4.5.3 to before 5.0.0, 5.2.6 to before 5.4.21, 6.0.0 to before 6.4.1, 7.0.0 to before 7.0.8, and 7.1.0 to before 7.1.11, files denied by server.fs.deny were sent if the URL ended with \ when the dev server is running on Windows. Only apps explicitly exposing the Vite dev server to the network and running the dev server on Windows were affected. This issue has been patched in versions 5.4.21, 6.4.1, 7.0.8, and 7.1.11.

VITE FILE LEAK via ?inline&import pre-6.2.4/6.1.3/6.0.13/5.4.16/4.5.11
CVE-2025-31125 5.3 - Medium - March 31, 2025

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.

Vite File Exfil via '?raw??' Bypass (<=6.2.3)
CVE-2025-30208 - March 24, 2025

Vite, a provider of frontend development tooling, has a vulnerability in versions prior to 6.2.3, 6.1.2, 6.0.12, 5.4.15, and 4.5.10. `@fs` denies access to files outside of Vite serving allow list. Adding `?raw??` or `?import&raw??` to the URL bypasses this limitation and returns the file content if it exists. This bypass exists because trailing separators such as `?` are removed in several places, but are not accounted for in query string regexes. The contents of arbitrary files can be returned to the browser. Only apps explicitly exposing the Vite dev server to the network (using `--host` or `server.host` config option) are affected. Versions 6.2.3, 6.1.2, 6.0.12, 5.4.15, and 4.5.10 fix the issue.

Vite: Reflected CORS & WS Origin Bypass (Before 6.0.9/5.4.12/4.5.6)
CVE-2025-24010 - January 20, 2025

Vite is a frontend tooling framework for javascript. Vite allowed any websites to send any requests to the development server and read the response due to default CORS settings and lack of validation on the Origin header for WebSocket connections. This vulnerability is fixed in 6.0.9, 5.4.12, and 4.5.6.

Vite DOM Clobbering XSS before 5.4.6 in cjs/iife/umd
CVE-2024-45812 - September 17, 2024

Vite a frontend build tooling framework for javascript. Affected versions of vite were discovered to contain a DOM Clobbering vulnerability when building scripts to `cjs`/`iife`/`umd` output format. The DOM Clobbering gadget in the module can lead to cross-site scripting (XSS) in web pages where scriptless attacker-controlled HTML elements (e.g., an img tag with an unsanitized name attribute) are present. DOM Clobbering is a type of code-reuse attack where the attacker first embeds a piece of non-script, seemingly benign HTML markups in the webpage (e.g. through a post or comment) and leverages the gadgets (pieces of js code) living in the existing javascript code to transform it into executable code. We have identified a DOM Clobbering vulnerability in Vite bundled scripts, particularly when the scripts dynamically import other scripts from the assets folder and the developer sets the build output format to `cjs`, `iife`, or `umd`. In such cases, Vite replaces relative paths starting with `__VITE_ASSET__` using the URL retrieved from `document.currentScript`. However, this implementation is vulnerable to a DOM Clobbering attack. The `document.currentScript` lookup can be shadowed by an attacker via the browser's named DOM tree element access mechanism. This manipulation allows an attacker to replace the intended script element with a malicious HTML element. When this happens, the src attribute of the attacker-controlled element is used as the URL for importing scripts, potentially leading to the dynamic loading of scripts from an attacker-controlled server. This vulnerability can result in cross-site scripting (XSS) attacks on websites that include Vite-bundled files (configured with an output format of `cjs`, `iife`, or `umd`) and allow users to inject certain scriptless HTML tags without properly sanitizing the name or id attributes. This issue has been patched in versions 5.4.6, 5.3.6, 5.2.14, 4.5.5, and 3.2.11. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Vite Arbitrary File Return via ?import&raw Bypass in @fs (V5.4.6-5.2.14)
CVE-2024-45811 - September 17, 2024

Vite a frontend build tooling framework for javascript. In affected versions the contents of arbitrary files can be returned to the browser. `@fs` denies access to files outside of Vite serving allow list. Adding `?import&raw` to the URL bypasses this limitation and returns the file content if it exists. This issue has been patched in versions 5.4.6, 5.3.6, 5.2.14, 4.5.5, and 3.2.11. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Vite FS Deny Bypass (caseinsensitive) <5.0.12/4.5.2/3.2.8/2.9.17
CVE-2024-23331 7.5 - High - January 19, 2024

Vite is a frontend tooling framework for javascript. The Vite dev server option `server.fs.deny` can be bypassed on case-insensitive file systems using case-augmented versions of filenames. Notably this affects servers hosted on Windows. This bypass is similar to CVE-2023-34092 -- with surface area reduced to hosts having case-insensitive filesystems. Since `picomatch` defaults to case-sensitive glob matching, but the file server doesn't discriminate; a blacklist bypass is possible. By requesting raw filesystem paths using augmented casing, the matcher derived from `config.server.fs.deny` fails to block access to sensitive files. This issue has been addressed in vite@5.0.12, vite@4.5.2, vite@3.2.8, and vite@2.9.17. Users are advised to upgrade. Users unable to upgrade should restrict access to dev servers.

Vite v<5.0.5 HTML Injection via transformIndexHtml
CVE-2023-49293 6.1 - Medium - December 04, 2023

Vite is a website frontend framework. When Vite's HTML transformation is invoked manually via `server.transformIndexHtml`, the original request URL is passed in unmodified, and the `html` being transformed contains inline module scripts (`<script type="module">...</script>`), it is possible to inject arbitrary HTML into the transformed output by supplying a malicious URL query string to `server.transformIndexHtml`. Only apps using `appType: 'custom'` and using the default Vite HTML middleware are affected. The HTML entry must also contain an inline script. The attack requires a user to click on a malicious URL while running the dev server. Restricted files aren't exposed to the attacker. This issue has been addressed in vite@5.0.5, vite@4.5.1, and vite@4.4.12. There are no known workarounds for this vulnerability.
