  "summary" : "Grafana Operator: Privilege escalation from namespace admin to cluster admin via GrafanaDashboard jsonnetLib fileName",
  "details" : "We have released version 5.24.0 of the Grafana Operator. This patch includes a MODERATE severity security fix for a path traversal/privilege escalation vulnerability in the Grafana Operator.\n\n\n### Summary\n\nThe 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.\n### Impact\n\nIt 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.\n\n### Affected versions\n\nAll Grafana Operator versions <= 5.23\n\n### Solutions and mitigations\n\nAll installations should be upgraded as soon as possible.\n\nAs a workaround, the following ValidatingAdmissionPolicy prevent the creation or modification of jsonnet based resources:\n```\napiVersion: admissionregistration.k8s.io/v1\nkind: ValidatingAdmissionPolicy\nmetadata:\n  name: \"prevent-jsonnet-dashboards\"\nspec:\n  failurePolicy: Fail\n  matchConstraints:\n    resourceRules:\n      - apiGroups: [\"grafana.integreatly.org\"]\n        apiVersions: [\"v1beta1\"]\n        operations: [\"CREATE\", \"UPDATE\"]\n        resources: [\"grafanadashboards\", \"grafanalibrarypanels\"]\n  validations:\n    - expression: \"!has(object.spec.jsonnetLib)\"\n---\napiVersion: admissionregistration.k8s.io/v1\nkind: ValidatingAdmissionPolicyBinding\nmetadata:\n  name: \"prevent-jsonnet-dashboards-clusterwide\"\nspec:\n  policyName: \"prevent-jsonnet-dashboards\"\n  validationActions: [Deny]\n```\n\n\n### Acknowledgement\n\nWe would like to thank [Artem Cherezov](https://github.com/cherez0ff) for responsibly disclosing the vulnerability.",
