Upgrade rack to version 2.2.13, 3.0.14, 3.1.12 or higher.
Overview
rack is 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.
Affected versions of this package are vulnerable to Relative Path Traversal in the can_serve() function in Rack::Static that enables local file inclusion. An attacker who knows the exact path to any file in the root: file directory can access it by supplying a path traversing pathname.
