Background
The zero package is an npm package that provides functionality for handling server files. It is used to fetch files from the server using URLs. However, versions prior to 1.0.6 are vulnerable to a Path Traversal vulnerability. This vulnerability arises due to insufficient input sanitization in URLs, allowing attackers to access server files by using relative paths when fetching files.
Vulnerability Detail
The Path Traversal vulnerability in zero allows attackers to bypass file access restrictions and retrieve sensitive server files. By manipulating the URL and using relative paths, an attacker can traverse the file system and access files that should not be accessible. This can lead to unauthorized disclosure of sensitive information or even remote code execution if the accessed files contain executable code. The vulnerability has a high severity rating (CWE-22) and can have significant security implications for applications using affected versions of the zero package.
