CVE-2025-68155Public exploitNetwork attack vector

Unauthenticated file read via unrestricted file URL

Published Dec 16, 2025 · Updated Dec 16, 2025

Path traversal in @vitejs/plugin-rsc before 0.5.8 allows remote attackers to read Node-accessible files through its development endpoint. The findSourceMapURL handler converts the filename query parameter from a file URL and passes the resulting path to fs.readFileSync without restricting it to the project directory. Exposure requires a running Vite development server with the RSC plugin enabled and network reachability; successful requests disclose only files readable by that Node.js process.
