Name of the Vulnerable Software and Affected Versions: simple-npm-registry versions (affected versions not specified)

Description: The issue allows an attacker to access the filesystem by exploiting a directory traversal vulnerability. This can be achieved by placing "../" in the URL, enabling the attacker to access files outside of the intended directory root, potentially leading to the disclosure of private files on the vulnerable system. For example, a malicious actor can send a request like "GET /../../../../../../../../../../etc/passwd HTTP/1.1" to access sensitive files.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, consider restricting access to the simple-npm-registry package, and only use it for local development. If the functionality is needed for production, it is recommended to use a different package instead.
