Technical details
The Vite development server checks file access restrictions (server.fs.deny) against URLs after query parameters have been stripped, but does not re-check against the original URL with query parameters intact. An unauthenticated attacker can append loader query parameters (?raw, ?import&raw, ?import&url&inline) to bypass the access control check and retrieve denied files that match server.fs.allow. The fix re-validates access against both the cleaned URL and the original URL with query parameters.
