Background
The dylmomo 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 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 dylmomo arises from its improper resolution of relative file paths. By exploiting this vulnerability, an attacker can craft requests that traverse directories and access files outside of the intended directory root. For example, an attacker can send a GET request with a crafted path to access sensitive files like /etc/passwd. This can result in the unauthorized disclosure of private information.
How To Fix
No fixed version is published for this vulnerability.

Conclusion
The dylmomo package is vulnerable to a directory traversal attack, which can lead to the unauthorized disclosure of private files. No patch is available for this vulnerability, so it is advised to use the package only for local development and switch to a different package for production if the functionality is needed.
