Name of the Vulnerable Software and Affected Versions: tinyserver2 versions prior to 0.6.0

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 resulting in 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: Update to v0.6.0 or later. As a temporary workaround, consider restricting access to sensitive files and directories to minimize the risk of exploitation.
