    Summary: Omniauth allows POST parameters to be stored in session

    Details: In strategy.rb in OmniAuth before 1.3.2, the authenticity_token value is improperly protected because POST (in addition to GET) parameters are stored in the session and become available in the environment of the callback phase.
