Release notes

Sourced from omniauth's releases.

Allow passing rack-protection configuration to default request_validation_phase

This release now properly allows an instance of OmniAuth::AuthenticityTokenProtection (with passed in rack-protection configuration) to be used as the request_validation_phase.

Thanks @jkowens #1027

If you haven't already read the release notes for v2.0.0, you should do so.

v2.0.0

Version 2.0 of OmniAuth includes some changes that may be breaking depending on how you use OmniAuth in your app.

Many thanks to the folks who contributed in code and discussion for these changes.

OmniAuth now defaults to only POST as the allowed request_phase method.

Hopefully, you were already doing this as a result of the warnings due to CVE-2015-9284.
For detailed context, see:
#960
#809
Resolving CVE-2015-9284

This change also includes an additional configurable phase: request_validation_phase.

Rack/Sinatra

By default, this uses rack-protection's AuthenticityToken class to validate authenticity tokens. If you are using a rack based framework like sinatra, you can find an example of how to add authenticity tokens to your view here.

Rails

Because Rails handles its CSRF protection in its RequestForgeryProtection class, and stores tokens in a non-vanilla-rack friendly way, you must pass a rails-friendly validator in instead, similar to what omniauth-rails_csrf_protection does.

Update: omniauth-rails_csrf_protection has released v1.0.0, which means if you're using this library already, you should be able to upgrade omniauth to the 2.0 series as long as omniauth-rails_csrf_protection is also upgraded '~> 1.0'

An example of creating your own non-dependency implementation is below, though I would recommend using the gem.

# Derived from https://github.com/cookpad/omniauth-rails_csrf_protection/blob/master/lib/omniauth/rails_csrf_protection/token_verifier.rb
# This specific implementation has been pared down and should not be taken as the most correct way to do this.
class TokenVerifier
  include ActiveSupport::Configurable
  include ActionController::RequestForgeryProtection
def call(env)
@request = ActionDispatch::Request.new(env.dup)
raise OmniAuth::AuthenticityError unless verified_request?
end
private
attr_reader :request
delegate :params, :session, to: :request
end
in an initializer
OmniAuth.config.request_validation_phase = TokenVerifier.new
