CVE-2026-11769

Estado: ModificadaMedia (6.4)—

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

Leer descripción completaMostrar menos

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:

### Acknowledgement

We would like to thank Artem Cherezov for responsibly disclosing the vulnerability.
