Background
The desafio 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, 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 desafio 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 /etc/passwd. This vulnerability has a moderate severity rating and is classified under CWE-22.
How To Fix
No fixed version is published for this vulnerability.
Unfortunately, there is no patch available for this vulnerability. It is recommended to use the desafio package only for local development purposes. If the functionality provided by desafio is required for production, it is advised to switch to a different package that does not have this vulnerability.
