CVE-2022-25895Public exploitNetwork attack vector

Arbitrary file read via unchecked request paths

Published Dec 21, 2022 · Updated Apr 16, 2025

Path traversal in lite-dev-server 3.2.7 and earlier allows remote attackers to read files outside the configured web root via crafted URLs. The HTTP request handler concatenates the configured folder with req.url and passes the resulting path directly to file and directory helpers without normalization or containment checks. No authentication or user interaction is required when the development server is network-reachable, and exposure is limited to readable files accessible to the server process.
