Vite is a frontend tooling framework for JavaScript. From 7.1.0 to before 7.3.2 and 8.0.5, 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. This vulnerability is fixed in 7.3.2 and 8.0.5.

 https://vulnerability.circl.lu/vuln/ghsa-v2wj-q39q-566r GHSA-v2wj-q39q-566r — Vite: `server.fs.deny` bypassed with queries 2026-10-01T20:21:25.482014+00:00

Affected: npm: vite

### 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. Confirm that the same files can be retrieved with query parameters (expect 200): <img width="2014" height="373" alt="image" src="https://github.com/user-attachments/assets/76bc2a6a-44f4-4161-ae47-eab5ae0c04a8" />
