| Description | 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. |
