Description
This Ruby on Rails web application is running in development mode. When you generate a Ruby on Rails application it will create three environments: development, production and test. In development mode, Rails is not as secure as it shows diagnostics pages that leak a lot of sensitive information about the application internals.
Remediation
It's recommended to configure your Rails application to run in production mode. Usually, the following command will run your application in production mode.
rails server -e production
