{"id":"CVE-2026-53487","summary":"Kite has an authenticated cluster RBAC bypass in /api/v1/overview","details":"Kite is a Kubernetes dashboard. Prior to version 0.12.3, authenticated Kite users with any role can request `/api/v1/overview` for a cluster that their roles do not permit by selecting that cluster with `x-cluster-name`. The overview route is registered before `middleware.RBACMiddleware()` and `GetOverview` only checks `len(user.Roles) \u003e 0`, so it returns aggregate Kubernetes inventory and capacity data from unauthorized clusters. Version 0.12.3 fixes the issue.","aliases":["GHSA-gvhc-wv3v-7pf8","GO-2026-5941"],"modified":"2026-08-27T11:30:57.839687903Z","published":"2026-08-21T21:35:41.451Z","related":["openSUSE-SU-2026:21483-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53487.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-862"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53487.json"},{"type":"ADVISORY","url":"https://github.com/kite-org/kite/security/advisories/GHSA-gvhc-wv3v-7pf8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53487"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kite-org/kite","events":[{"introduced":"0"},{"fixed":"a011abe757ada6a5834c3ad3e8f63d7495994ca8"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"0.12.3"}]}}],"versions":["v0.12.2","v0.12.1","v0.12.0","v0.11.0","v0.10.0","v0.9.0","v0.8.1","v0.8.0","v0.7.8","v0.7.7","v0.7.6","v0.7.5","v0.7.4","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.9","v0.6.8","v0.6.7","v0.6.6","v0.6.5","v0.6.4","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.5.0","helm-chart-0.5.0","v0.4.1","helm-chart-0.4.1","v0.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53487.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
