Description Michael Kaplan 2021-03-15 12:03:05 UTC

Grafana Enterprise 6.6.0 introduced a new HTTP API endpoint for usage insights which allows any unauthenticated user to send an unlimited number of requests to the endpoint, leading to a denial of service (DoS) attacks against Grafana Enterprise instances. We have reserved CVE-2021-28148 for this issue. This vulnerability allows users to perform DoS attacks.
