Overview
Affected versions of this package are vulnerable to User Impersonation via the request.params[:subject_id] parameter when no authenticate_proc is configured. An attacker can gain unauthorized access and impersonate other users by supplying arbitrary subject IDs in the request parameters. This is only exploitable if the built-in ActionCable connection is mounted without configuring authenticate_proc.
