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 \u2014 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."}], "lastModified": "2026-06-17T10:46:07.213", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:kyverno:kyverno:*:-:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "6574A7FA-CE7D-4EB6-B036-044E07DB453A", "versionEndExcluding": "1.17.2"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
