Omniauth::Protect

Protects your Rails app from Omniauth request phase CSRF vulnerability

Add this line to your application's Gemfile:

gem 'omniauth-protect'

And then execute:

$ bundle

Or install it yourself as:

$ gem install omniauth-protect

Add this line to your config/application.rb to use the middleware

config.middleware.use Omniauth::Protect::Middleware

Or use the validator on it's own

Omniauth::Protect::Validator.new(request.env, encoded_masked_token).valid_csrf_token?

omniauth-protect 1.0.0 supports rails < 5.2.4.3 and between 6.0.0 and 6.0.3

omniauth-protect 2.0.0 supports rails = 5.2.4.3

omniauth-protect 3.0.0 supports rails > 6.0.3.1

You need to create an initiliazer like config/initializers/omniauth_protect.rb for configuration

Omniauth::Protect.config[:message] = 'CSRF detected, Access Denied'
Omniauth::Protect.config[:paths] = ['/auth/twitter', '/auth/google' ,'/auth/github']
Omniauth::Protect.configure
