Name of the Vulnerable Software and Affected Versions: yzt versions (affected versions not specified)

Description: The issue concerns a directory traversal problem, allowing an attacker to access the filesystem by including "../" in the URL. This vulnerability enables a malicious actor to access files outside the intended directory root, potentially leading to the disclosure of private files on the vulnerable system. For example, an attacker can send a GET request to access sensitive files, such as /../../../../../../../../../../etc/passwd.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability. It is recommended that yzt is only used for local development, and if the functionality is needed for production, a different package is used instead.
