Background
The yzt 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, 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
The vulnerability in yzt arises from its resolution of relative file paths. By manipulating the file path in a specific way, an attacker can traverse directories and access files outside of the intended scope. For example, an attacker can send a GET request with a crafted file path to retrieve sensitive files, such as the /etc/passwd file. This vulnerability has a high severity rating and is classified as CWE-22.
How To Fix

Conclusion
The yzt package is vulnerable to a directory traversal attack, which can result in the disclosure of sensitive files. While no patch is available, it is recommended to only use this package for local development purposes. For production use, it is advised to switch to an alternative package that does not have this vulnerability. For further support on vulnerability remediation, please contact DevNack.com.
