CVE-2021-41244: Grafana Fine-grained access control vulnerability

May 14, 2024

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.
