Background
The xtalk package is an npm module that provides functionality for cross-platform communication between different processes. It allows developers to establish communication channels and exchange messages between processes. However, versions of xtalk prior to 0.0.2 are vulnerable to directory traversal attacks, which can lead to unauthorized access to the filesystem.
Vulnerability Detail
The vulnerability in xtalk arises from insufficient input validation. Attackers can exploit this flaw by including "../" in the URL, which allows them to navigate to directories outside the intended scope. By leveraging directory traversal, an attacker can access sensitive files on the filesystem, potentially leading to unauthorized disclosure of information or remote code execution.
How To Fix
No fixed version is published for this vulnerability.

Conclusion
The xtalk package is vulnerable to directory traversal attacks, which can lead to unauthorized access to the filesystem. Since no patch is available and the package has not been updated for several years, it is recommended to avoid using xtalk and find an alternative package that offers similar functionality without this vulnerability.
