Background
The simplehttpserver package is an npm module that provides a simple HTTP server for serving static files. It allows developers to quickly set up a local web server for testing and development purposes. However, all versions of simplehttpserver are vulnerable to a Path Traversal vulnerability. This vulnerability enables an attacker to access files outside the webroot by exploiting symlink navigation in the URL.
Vulnerability Detail
