A flaw was found in Grafana. This flaw allows a malicious user with the authorization to log into a Grafana instance via a configured OAuth IdP to take over an existing Grafana account under certain conditions.
As a workaround, it is possible to disable any OAuth login or ensure that all users authorized to log in via OAuth have a corresponding user account in Grafana linked to their email address.
