{"id":"CVE-2026-41068","summary":"Kyverno: Cross-Namespace Read Bypasses RBAC Isolation (CVE-2026-22039 Incomplete Fix)","details":"Kyverno is a policy engine designed for cloud native platform engineering teams. The patch for CVE-2026-22039 fixed cross-namespace privilege escalation in Kyverno's `apiCall` context by validating the `URLPath` field. However, the ConfigMap context loader has the identical vulnerability — the `configMap.namespace` field accepts any namespace with zero validation, allowing a namespace admin to read ConfigMaps from any namespace using Kyverno's privileged service account. This is a complete RBAC bypass in multi-tenant Kubernetes clusters. An updated fix is available in version 1.17.2.","aliases":["BIT-kyverno-2026-41068","GHSA-cvq5-hhx3-f99p","GO-2026-5337"],"modified":"2026-07-15T01:49:00.307700483Z","published":"2026-04-24T03:14:27.640Z","related":["CGA-4q89-5h43-8pwv"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41068.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-863"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41068.json"},{"type":"ADVISORY","url":"https://github.com/kyverno/kyverno/security/advisories/GHSA-cvq5-hhx3-f99p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41068"},{"type":"FIX","url":"https://github.com/kyverno/kyverno/commit/bbf3e5c01391d612968440659028ae98e565a777"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kyverno/kyverno","events":[{"introduced":"0"},{"fixed":"f64c0f5820a022d354c77316785d08511d2a5cc4"},{"fixed":"bbf3e5c01391d612968440659028ae98e565a777"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.17.2"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:kyverno:kyverno:*:-:*:*:*:*:*:*"}}],"versions":["v1.17.2-rc.1","kyverno-policies-chart-3.7.2-rc.1","kyverno-chart-3.7.2-rc.1","v1.17.1","kyverno-policies-chart-3.7.1","kyverno-chart-3.7.1","v1.17.1-rc.1","kyverno-policies-chart-3.7.1-rc.1","kyverno-chart-3.7.1-rc.1","v1.17.0","kyverno-policies-chart-3.7.0","kyverno-chart-3.7.0","kyverno-policies-chart-3.7.0-rc.3","kyverno-chart-3.7.0-rc.3","v1.17.0-rc.3","kyverno-policies-chart-3.7.0-rc.2","kyverno-chart-3.7.0-rc.2","v1.17.0-rc.2","kyverno-policies-chart-3.7.0-rc.1","kyverno-chart-3.7.0-rc.1","v1.17.0-rc.1","1.9-dev","1.8-dev","1.7-dev","test-dev","1.6-dev","helm-chart-v2.1.3","v1.5.0-rc1","helm-chart-v2.1.0","v1.4.3","helm-chart-v2.0.3","v1.4.3-rc2","helm-chart-v2.0.3-rc2","v1.4.3-rc1","helm-chart-v2.0.3-rc1","v1.4.2","v1.4.2-rc4","v1.4.2-rc3","v1.4.2-rc2","v1.4.2-rc1","v1.4.1","v1.4.0-rc4","v1.4.0","v1.4.0-rc3","v1.4.0-rc2","v1.4.0-rc1","v1.3.6","v1.3.6-rc5","v1.3.6-rc4","v1.3.6-rc3","v1.3.6-rc2","v1.3.6-rc1","v1.3.5","v1.3.5-rc5","v1.3.5-rc4","v1.3.5-rc3","v1.3.5-rc2","v1.3.5-rc1","v1.3.4","v1.3.4-rc1","v1.3.3","v1.3.2","v1.3.2-rc3","v1.3.2-rc2","v1.3.2-rc1","v1.3.1","v1.3.0","v1.3.0-rc12","v1.3.0-rc11","v1.3.0-rc10","1.3.0-rc10","v1.3.0-rc9","v1.3.0-rc8","v1.3.0-rc7","v1.3.0-rc6","v1.3.0-rc5","v1.3.0-rc4","v1.3.0-rc3","v1.3.0-rc2","v1.3.0-rc1","v1.2.1","v1.2.0","v1.1.12","v1.1.11","v1.1.10","v1.1.9","v1.1.8","v1.1.7","v1.1.7-rc4","v1.1.7-rc3","v1.1.7-rc2","v1.1.7-rc1","v1.1.6","v1.1.6-rc5","v1.1.6-rc4","v1.1.6-rc3","v1.1.6-rc2","v1.1.6-rc1","v1.1.5","v1.1.4","v1.1.4-rc1","v1.1.3","v1.1.3-rc1","v1.1.2","v1.1.1","v1.0.0","v1.0.0-rc1","v0.11.0","v0.10.0","v0.9.1","v0.9.0","v0.8.0","v0.7.1","v0.7.0","v0.5.0","v0.4.0","v0.3.0","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-41068.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"}]}
