Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-fcw4-wwqm-m8cf. This link is maintained to preserve external references.
Original Description
We have released version 5.24.0 of the Grafana Operator. This patch includes a CRITICAL 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:
