As a result, it is possible to bypass the [`server.fs.strict`](https://vite.dev/config/server-options#server-fs-strict) allow list and retrieve `.map` files located outside the project root, provided they can be parsed as valid source map JSON.\n\n### PoC\n1. Create a minimal PoC sourcemap outside the project root\n    ```bash\n    cat > /tmp/poc.map <<'EOF'\n    {\"version\":3,\"file\":\"x.js\",\"sources\":[],\"names\":[],\"mappings\":\"\"}\n    EOF\n    ```\n2. Start the Vite dev server (example)\n    ```bash\n    pnpm -C playground/fs-serve dev --host 127.0.0.1 --port 18080\n    ```\n3.
