{"id":"BIT-kyverno-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":["CVE-2026-41068","GHSA-cvq5-hhx3-f99p","GO-2026-5337"],"modified":"2026-09-08T08:47:40.340263278Z","published":"2026-04-28T08:42:41.880Z","database_specific":{"cpes":["cpe:2.3:a:kyverno:kyverno:*:*:*:*:*:go:*:*"],"severity":"High"},"references":[{"type":"FIX","url":"https://github.com/kyverno/kyverno/commit/bbf3e5c01391d612968440659028ae98e565a777"},{"type":"ADVISORY","url":"https://github.com/kyverno/kyverno/security/advisories/GHSA-cvq5-hhx3-f99p"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41068"}],"affected":[{"package":{"name":"kyverno","ecosystem":"Bitnami","purl":"pkg:bitnami/kyverno"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.17.2"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/kyverno/BIT-kyverno-2026-41068.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
