The same permission checks are made for sys.change_tracking_databases as are made for sys.databases. If the caller of sys.change_tracking_databases is not the owner of the database, the minimum permissions that are required to see the corresponding row are ALTER ANY DATABASE or VIEW ANY DATABASE server-level permission, or CREATE DATABASE permission in the master database or current database.
