This link is maintained to preserve external references.\n\n## Original Description\nWe 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.\n\n\n\n### Summary\n\n\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\n\n\n### Impact\n\n\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\n\n### Affected versions\n\n\n\nAll Grafana Operator versions <= 5.23\n\n\n\n### Solutions and mitigations\n\n\n\nAll installations should be upgraded as soon as possible.\n\n\n\nAs a workaround, the following ValidatingAdmissionPolicy prevent the creation or modification of jsonnet based resources:\n\n\n\napiVersion: admissionregistration.k8s.io/v1\n\n\n\nkind: ValidatingAdmissionPolicy\n\n\n\nmetadata:\n\n  name: \"prevent-jsonnet-dashboards\"\n\n\nspec:\n\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\n\n---\n\n\n\napiVersion: admissionregistration.k8s.io/v1\n\n\n\nkind: ValidatingAdmissionPolicyBinding\n\n\n\nmetadata:\n\n  name: \"prevent-jsonnet-dashboards-clusterwide\"\n\n\nspec:\n\n  policyName: \"prevent-jsonnet-dashboards\"\n  validationActions: [Deny]\n\n\n### Acknowledgement\n\n\n\nWe would like to thank Artem Cherezov for responsibly disclosing the vulnerability.\n\n## Affected packages\n\n- `github.com/grafana/grafana-operator <= 5.23.0`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"sunlit","depthScore":28,"depthScoreParts":{"impact":27.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
