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. On
Grafana instances using an external authentication service and having the
EditorsCanAdmin feature enabled, this vulnerability allows any
authenticated user to add external groups to any existing team. This can be
used to grant a user team permissions that the user isn’t supposed to have.
