Vite: `server.fs.deny` bypassed with queries

### Summary The contents of files that are specified by [`server.fs.deny`](https://vite.dev/config/server-options#server-fs-deny) can be returned to the browser. ### Impact Only apps that match the following conditions are affected: - explicitly exposes the Vite dev server to the network (using `--host` or [`server.host` config option](https://vitejs.dev/config/server-options.html#server-host)) - the sensitive file exists in the allowed directories specified by [`server.fs.allow`](https://vite.dev/config/server-options#server-fs-allow) - the sensitive file is denied with a pattern that matches a file by [`server.fs.deny`](https://vite.dev/config/server-options#server-fs-deny) ### Details On the Vite dev server, files that should be blocked by `server.fs.deny` (e.g., `.env`, `*.crt`) can be retrieved with HTTP 200 responses when query parameters such as `?raw`, `?import&raw`, or `?import&url&inline` are appended. ### PoC 1. Start the dev server: `pnpm exec vite root --host 127.0.0.1 --port 5175 --strictPort` 2. Confirm that `server.fs.deny` is enforced (expect 403): `curl -i http://127.0.0.1:5175/src/.env | head -n 20` <img width="3944" height="1092" alt="image" src="https://github.com/user-attachments/assets/ecb9f2e0-e08f-4ac7-b194-e0f988c4cd4f" /> 3.
