Release 9.4.17 with the security patch:

H2: Cross-organization permission escalation by an organization administrator (CVE-2023-4822)


Vulnerable versions of Grafana are incorrectly assessing permissions to update cross-organization roles and role assignments. Therefore users with administrator permissions in one organization can change cross-organization role permissions and cross-organization role assignments.

This vulnerability impacts instances with more than one organization running Grafana Enterprise versions.

No Grafana Cloud instances are impacted because the platform is limited to a single organization.

The CVSS score for this vulnerability is 6.7 Medium.


If exploited, an attacker who has the Organization Admin role in any organization can elevate their permissions across all organizations, elevate other users’ permissions in all organizations, or limit other users’ permissions in all organizations.

The vulnerability, however, does not allow the attacker to become a member of an organization that they are not already a member of, nor can they add any other user to an organization that the attacker is not a member of already.

Impacted versions

The vulnerability impacts instances with more than one organization running Grafana Enterprise versions:

  • 8.0.0 to 10.0.0 with RBAC enabled
  • 10.0.0 to 10.1.2
  • 10.1.4

You can check if role-based access control (RBAC) is enabled by calling GET /api/access-control/status. If the endpoint is found and returns "enabled": true, role-based access control is enabled on your instance.

Solutions and mitigations

If your instance is vulnerable, we strongly recommend upgrading to one of the patched versions as soon as possible.

If you cannot upgrade now, you should limit the Organization Administrator privileges only to trusted users who will not abuse this vulnerability.
