Background
The datachannel-client 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 a malicious actor 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 datachannel-client arises from its resolution of relative file paths. By exploiting this vulnerability, an attacker can craft a request that includes a path traversal sequence, such as '../', 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 disclosure of sensitive information.
How To Fix
No fixed version is published for this vulnerability.
