Background
The uv-tj-demo package is an npm package used for local development. It provides functionality for resolving relative file paths. However, it is vulnerable to a directory traversal attack, which allows an attacker to access files outside of the intended directory root. This can lead to the disclosure of private files on the vulnerable system.
Vulnerability Detail
