Doorkeeper version 5.0.0 and later contains an information disclosure
vulnerability that allows an attacker to retrieve the client secret only
intended for the OAuth application owner. After authorizing the application
and allowing access, the attacker simply needs to request the list of their
authorized applications in a JSON format (usually GET
/oauth/authorized_applications.json). An application is vulnerable if the
authorized applications controller is enabled.
