CVE-2017-16097: Directory Traversal in tiny-http

The vulnerability stems from improper path resolution when handling HTTP requests. The advisory explicitly states that the package resolves relative paths without adequate safeguards. In Node.js servers, the request handler that maps URL paths to filesystem paths (typically using methods like path.join() or path.resolve()) is the primary suspect. While the exact implementation isn't visible, the pattern matches classic path traversal vulnerabilities where user input is directly concatenated with a base directory without validation. The high confidence comes from the vulnerability's clear root cause (CWE-22) and the explicit PoC demonstrating traversal via URL manipulation.
