{"id":"CVE-2026-62246","summary":"Kamaji: TenantControlPlane namespace/name collision binds two tenants to the same SQL datastore schema + DB user, breaking per-tenant isolation","details":"Kamaji is the Hosted Control Plane Manager for Kubernetes. Prior to 26.7.4-edge, Kamaji derives a TenantControlPlane datastore schema, database user, and etcd key prefix from a lossy namespace-and-name normalization in GetDefaultDatastoreSchema() and GetDefaultDatastoreUsername(), allowing distinct tenants with colliding normalized identifiers to share control-plane state and read, modify, or destroy another tenant's Kubernetes data. This issue is fixed in version 26.7.4-edge.","aliases":["GHSA-4f3f-65vx-r34f"],"modified":"2026-08-02T03:32:19.629742749Z","published":"2026-07-30T21:06:14.556Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-284","CWE-653"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/62xxx/CVE-2026-62246.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/62xxx/CVE-2026-62246.json"},{"type":"ADVISORY","url":"https://github.com/clastix/kamaji/security/advisories/GHSA-4f3f-65vx-r34f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-62246"},{"type":"FIX","url":"https://github.com/clastix/kamaji/commit/4232a9df7ccd08075c26191f59566202042543a9"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/clastix/kamaji","events":[{"introduced":"0"},{"fixed":"4232a9df7ccd08075c26191f59566202042543a9"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"26.7.4-edge"}]}}],"versions":["26.7.3-edge","26.7.2-edge","26.6.5-edge","26.6.4-edge","26.6.3-edge","26.6.2-edge","26.6.1-edge","26.5.5-edge","26.5.4-edge","26.5.3-edge","26.5.2-edge","26.4.5-edge","26.4.4-edge","26.4.3-edge","26.4.2-edge","26.3.6-edge","26.3.5-edge","26.3.4-edge","26.3.3-edge","26.3.2-edge","edge-26.2.5","edge-26.2.4","edge-26.2.3","edge-26.2.2","edge-26.1.5","edge-26.1.4","edge-26.1.3","edge-26.1.2","edge-25.12.5","edge-25.12.4","edge-25.12.3","edge-25.12.2","edge-25.12.1","edge-25.11.5","edge-25.11.4","edge-25.11.3","edge-25.11.2","edge-25.10.5","edge-25.10.4","edge-25.10.3","edge-25.10.2","edge-25.9.5","edge-25.9.4","edge-25.9.3","edge-25.9.2","edge-25.9.1","edge-25.8.5","edge-25.8.4","edge-25.8.3","edge-25.8.2","edge-25.7.5","edge-25.7.3","edge-25.7.2","edge-25.7.1","edge-25.4.1","edge-25.3.2","edge-25.03.1","edge-24.12.1","edge-24.10.1","edge-24.9.2","edge-24.9.1","edge-24.8.2","edge-24.8.1","edge-24.7.1","v1.0.0","helm-v1.0.0","v0.6.1","helm-v0.16.1","v0.6.0","helm-v0.16.0","v0.5.0","helm-v0.15.2","v0.4.2","helm-v0.15.1","helm-v0.15.0","v0.4.1","helm-v0.14.1","v0.4.0","helm-v0.14.0","v0.3.6","helm-v0.13.1","helm-v0.13.0","helm-v0.12.9","helm-v0.12.8","v0.3.5","helm-v0.12.7","helm-v0.12.6","v0.3.4","helm-v0.12.5","v0.3.3","helm-v0.12.4","v0.3.2","helm-v0.12.3","v0.3.1","helm-v0.12.2","helm-v0.12.1","v0.3.0","helm-v0.12.0","v0.2.3","helm-v0.11.5","v0.2.2","helm-v0.11.4","helm-v0.11.3","v0.2.1","helm-v0.11.2","helm-v0.11.1","v0.2.0","helm-v0.11.0","v0.2.0-rc0","helm-v0.10.2","helm-v0.10.1","v0.1.1","helm-v0.10.0","helm-v0.9.4","helm-v0.9.3","v0.1.0","helm-v0.9.2","helm-v0.9.1","helm-v0.8.0","helm-v0.7.0","helm-v0.6.0","helm-v0.5.0","helm-v0.4.0","helm-v0.3.0","helm-v0.2.0","v0.1.0-rc0","v0.0.2-rc0","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-62246.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
