Background
yyooopack is an npm package used for local development. It provides functionality for resolving file paths. However, it is vulnerable to a directory traversal attack. This means that an attacker can exploit this vulnerability to access files outside of the intended directory root. This can lead to the disclosure of sensitive files on the affected system.
Vulnerability Detail
The vulnerability in yyooopack 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 like GET /../../../etc/passwd to retrieve the contents of the /etc/passwd file. This can result in the exposure of sensitive information, such as user credentials or system configuration files.
How To Fix
No fixed version is published for this vulnerability.
