Name of the Vulnerable Software and Affected Versions: liuyaserver (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, giving access to 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. It is recommended that liuyaserver is only used for local development, and if the functionality is needed for production, a different package is used instead.
