On Nov. 2, during an internal security audit, we discovered that when the fine-grained access control beta feature is enabled and there is more than one organization in the Grafana instance, Grafana 8.0 introduced a mechanism which allowed users with the Organization Admin role to list, add, remove, and update users’ roles in other organizations in which they are not an admin.
Fixed in 8.2.4
All installations between v8.0 and v8.2.3 that have fine-grained access control beta enabled and more than one organization should be upgraded as soon as possible. If you cannot upgrade, you should turn off the fine-grained access control using a feature flag.
Grafana Cloud instances have not been affected by the vulnerability.
