Description

Cloud Foundry UAA, versions 60 prior to 66.0, contain an authorization logic error. In environments with multiple identity providers that contain accounts across identity providers with the same username, a remote authenticated user with access to one of these accounts may be able to obtain a token for an account of the same username in the other identity provider.
