Background
quickserver is an npm package used for local development and production purposes. It provides functionality for handling server requests. However, it is vulnerable to a directory traversal attack, 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 quickserver arises from the way it resolves relative file paths. By exploiting this vulnerability, an attacker can craft a request that includes additional directory traversal sequences (e.g., '../') to access files outside of the intended directory root. For example, an attacker could send a GET request to access the '/etc/passwd' file on the system. This can result in the unauthorized disclosure of sensitive information.
How To Fix
No fixed version is published for this vulnerability.

Conclusion
In conclusion, quickserver is vulnerable to a directory traversal attack, which can result in the unauthorized disclosure of sensitive files. While no patch is available, it is advised to limit the usage of quickserver to local development and consider alternative packages for production.
