BIT-KYVERNO-2026-100706 kyverno before 1.19.1 Privilege Escalation via Policy apiCall urlPath

kyverno before 1.19.1 fails to properly validate URL-encoded path segments in Policy apiCall urlPath, allowing namespace tenants to bypass the per-namespace clamp and create objects in other namespaces as the admission-controller ServiceAccount. Attackers can exploit this by using percent-encoded...
