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 \u003c= 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disclosing the vulnerability.","modified":"2026-06-19T21:00:15.689275580Z","published":"2026-06-13T06:30:23Z","withdrawn":"2026-06-19T20:50:34Z","database_specific":{"cwe_ids":["CWE-22"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-06-19T20:50:34Z","nvd_published_at":"2026-06-13T06:16:14Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-11769"},{"type":"WEB","url":"https://grafana.com/security/security-advisories/cve-2026-11769"}],"affected":[{"package":{"name":"github.com/grafana/grafana-operator","ecosystem":"Go","purl":"pkg:golang/github.com/grafana/grafana-operator"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"5.23.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-v82c-5c2q-hx9g/GHSA-v82c-5c2q-hx9g.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
