vite allows server.fs.deny bypass via backslash on Windows
Summary
Files denied by server.fs.deny were sent if the URL ended with \ when the dev server is running on Windows.
Impact
Only apps that match the following conditions are affected:
- explicitly exposes the Vite dev server to the network (using --host or
server.hostconfig option) - running the dev server on Windows
Details
server.fs.deny can contain patterns matching against files (by default it includes .env, .env.*, *.{crt,pem} as such patterns). These patterns were able to bypass by using a back slash(\). The root cause is that fs.readFile('/foo.png/') loads /foo.png.
