Background
liyujing 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, where a malicious actor can 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 liyujing arises from its improper handling of relative file paths. By exploiting this vulnerability, an attacker can construct a request that traverses directories and accesses files outside of the intended directory root. For example, an attacker can send a GET request to access the '/etc/passwd' file using multiple '../' sequences to navigate to the root directory. This can result in the disclosure of sensitive information stored in files on the system.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As there is no patch available, the best workaround is to avoid using liyujing in production environments. Instead, consider using an alternative package that provides similar functionality but does not suffer from the directory traversal vulnerability.
Conclusion
liyujing is vulnerable to a directory traversal attack, which can result in the disclosure of sensitive files on the system. Unfortunately, there is no patch available for this vulnerability. It is recommended to only use liyujing for local development purposes and switch to a different package for production if the functionality is needed.
