Background
The serverliujiayi1 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 vulnerability, which allows malicious actors to access files outside of the intended directory root. This can lead to the disclosure of private files on the vulnerable system.
Vulnerability Detail
The vulnerability in serverliujiayi1 arises from its improper resolution of relative file paths. By exploiting this vulnerability, an attacker can craft a malicious request to access files outside of the intended directory root. For example, an attacker can use a GET request with a crafted path to access sensitive files such as /etc/passwd. This can result in the unauthorized disclosure of private information.
