Ruby Rack 3.x < 3.1.21 / 3.2.x < 3.2.6 Multiple Vulnerabilities

The version of the Rack Ruby library installed on the remote host is 3.0.0.beta1 or later but prior to 3.1.21, or is 3.2.0 or later but prior to 3.2.6. It is, therefore, affected by multiple vulnerabilities: - Rack::Multipart::Parserhandlemimehead parses quoted multipart parameters using repeated...

Inefficient Algorithmic Complexity

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 singl...

Rack security vulnerabilities

Rack is a modular Ruby web server interface developed by Rack authors. Versions of Rack prior to 3.1.21 and 3.2.6 contained security vulnerabilities. These vulnerabilities stemmed from improper handling of multi-part parameters with quotes during the parsing of...
