-------- DESCRIPTION
---------------------------------------------------------

OAuth2 Client is an API support module, enabling other modules to connect to
services using OAuth2 authentication.

Within its API code the Client class exposes variables in an error message,
which originate from a third party source without proper sanitisation thus
leading to a Cross Site Scripting vulnerability.
