Rack::Taint

Rack::Taint is Rack middleware to taint the the query string (and thus
GET parameters), input (and thus POST parameters), headers (and thus
cookies), and everything else that comes in on a request. Among other
use cases, this may prove helpful as a component in a scheme that
limits mass assignment in Rails.

Installation

Add this line to your application’s Gemfile:

gem 'rack-taint'

On Rails, the Railtie takes care of everything else. On everything
else, you’ll need to add the Rack::Taint middleware to the stack
yourself.
