Background
The serverwzl package is an npm package used for local development. It provides functionality for resolving file paths. However, it is vulnerable to a directory traversal attack, where a malicious actor can access files outside of the intended directory root. This can lead to the disclosure of private files on the vulnerable system.
Vulnerability Detail
