CVE-2022-44570 - Medium Severity Vulnerability

Vulnerable Library - rack-2.2.3.gem

Rack provides a minimal, modular and adaptable interface for developing web applications in Ruby. By wrapping HTTP requests and responses in the simplest way possible, it unifies and distills the API for web servers, web frameworks, and software in between (the so-called middleware) into a single method call.
