Published Jun 13, 2026 CVSS 4.0 · 6.4 Medium EPSS < 1% KEV · Not listed
Description
We have released version 5.24.0 of the Grafana Operator. This patch includes a MEDIUM severity security fix for a path traversal/privilege escalation vulnerability in the Grafana Operator.


### Summary

The Grafana Operator supports loading dashboards & library panels using the jsonnet data templating language. The jsonnet expression is evaluated in the context of the operator manager pod.


### Impact

It is possible for a malicious user who can create Dashboard or LibraryPanel resources for a Grafana instance to obtain the Kubernetes service account token of the Grafana Operator manager.

### Affected versions

All Grafana Operator versions <= 5.23

### Solutions and mitigations

All installations should be upgraded as soon as possible.

As a workaround, the following ValidatingAdmissionPolicy prevent the creation or modification of jsonnet based resources:

apiVersion: admissionregistration.k8s.io/v1
kind: ValidatingAdmissionPolicy
metadata:
name: "prevent-jsonnet-dashboards"
spec:
failurePolicy: Fail
matchConstraints:
resourceRules:
- apiGroups: ["grafana.integreatly.org"]
apiVersions: ["v1beta1"]
operations: ["CREATE", "UPDATE"]
resources: ["grafanadashboards", "grafanalibrarypanels"]
validations:
- expression: "!has(object.spec.jsonnetLib)"
---
apiVersion: admissionregistration.k8s.io/v1
