This patch includes a MEDIUM 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\n\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 for responsibly disclosing the vulnerability.","published":"2026-06-13T04:17:41.099Z","modified":"2026-08-13T03:51:53.969559322Z","cvss":null,"epss":{"score":0.00361,"percentile":0.29058,"asOf":"2026-08-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/grafana/grafana-operator/v5","fixedVersion":"5.24.0"},{"ecosystem":"Go","name":"github.com/grafana/grafana-operator","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/11xxx/CVE-2026-11769.json"},{"type":"ADVISORY","url":"https://grafana.com/security/security-advisories/cve-2026-11769"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-11769"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T03:51:53.969559322Z"}}
