Grafana Enterprise 8.4.6 released with high severity security fix

12 Apr 2022 3 min read

Today we are releasing Grafana Enterprise 8.4.6. This patch release includes a high severity security fix that affects Grafana Enterprise versions from v8.1.0-beta1 through v8.4.5.

Release v8.4.6, only containing a security fix:

Privilege escalation (CVE-2022-24812)

Summary

On April 3, during an internal security audit, we discovered a security vulnerability impacting Grafana Enterprise instances which have the fine-grained access control beta feature enabled and have at least two API Keys with different roles.

This vulnerability allowed clients using the Grafana API Key for making requests to gain permissions of the previous requests, which could lead to an escalation of privileges, depending on the permissions of the previous request. We have received CVE-2022-24812 for this issue. The CVSS score for this vulnerability is 8.0 High (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H) for Grafana Enterprise versions 8.1.0-beta1 to 8.4.5.

Grafana OSS is not impacted by the vulnerability.

Affected versions with high severity

Grafana Enterprise 8.1.0-beta1 to 8.4.5

Solutions and mitigations

All Grafana Enterprise installations between v8.1.0-beta1 and v8.4.5 that have fine-grained access control beta enabled should be upgraded as soon as possible. If you cannot upgrade, you should turn off the fine-grained access control using a feature flag.

All Grafana Cloud instances have already been patched with the fix.

As always, we closely coordinated with all cloud providers licensed to offer Grafana Pro. They have received early notification under embargo and confirmed that their offerings are secure at the time of this announcement. In alphabetical order, this is applicable to Amazon Managed Grafana and Azure Managed Grafana.
