Overview

doorkeeper is an Oauth 2.0 provider for Rails and Grape.

Affected versions incorrectly implement Oauth 2.0 Token Revocation (RFC 7009). Specifically, public clients making an unauthenticated calls to revoke a token would not have their tokens revoked. In addition, a compromised confidential client can be used to revoke tokens of other users.
