Description
The team sync HTTP API in Grafana Enterprise 6.x before 6.7.6, 7.x before 7.3.10, and 7.4.x before 7.4.5 has an Incorrect Access Control issue and accessible without any authentication. On Grafana instances using an external authentication service, this vulnerability allows any authenticated user to add external groups to existing teams. This can be used to grant a user team permissions that the user isn\'t supposed to have and leading to a denial of service (DoS) attack against a Grafana Enterprise instance.
