Upgrade rack to version 2.2.11, 3.0.12, 3.1.10 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 Improper Output Neutralization for Logs through the Rack::CommonLogger process. An attacker can manipulate log entries by crafting input that includes newline characters to insert fraudulent entries or obscure real activity.
