One of the usage insights HTTP API endpoints in Grafana Enterprise 6.x
before 6.7.6, 7.x before 7.3.10, and 7.4.x before 7.4.5 is accessible
without any authentication. This allows any unauthenticated user to send an
unlimited number of requests to the endpoint, leading to a denial of
service (DoS) attack against a Grafana Enterprise instance.
