Description

### 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](https://vitejs.dev/config/server-options.html#server-host)) 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`
