  "title": "Vite has a `server.fs.deny` bypassed for `inline` and `raw` with `?import` query",
  "summary": "### Summary\n\nThe contents of arbitrary files can be returned to the browser.\n\n### Impact\nOnly 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.\n\n### Details\n\n- base64 encoded content of non-allowed files is exposed using `?inline&import` (originally reported as `?import&?inline=1.wasm?init`)\n- content of non-allowed files is exposed using `?raw?import`\n\n`/@fs/` isn't needed to reproduce the issue for files inside the project root.\n\n### PoC\n\nOriginal report (check details above for simplified cases):\n\nThe ?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\n```\n$ npm create vite@latest\n$ cd vite-project/\n$ npm install\n$ npm run dev\n```\n\nExample full URL `http://localhost:5173/@fs/C:/windows/win.ini?import&?inline=1.wasm?init`",
