Description

This module provides an OAuth2 client.

The module does not check the validity of the state parameter, during server-side flow, before getting a token. This may allow a malicious user to feed a fake access_token to another user, and subsequently provide him fake data from the server. This page explains it in more details: http://www.twobotechnologies.com/blog/2014/02/importance-of-state-in-oau...
