Impact
Kyverno before 1.19.1 contains a namespace isolation bypass in the apiCall context entry of namespaced Policy resources due to inconsistent path interpretation between validation and execution. A low-privilege tenant can use percent-encoded dot-segments in urlPath to bypass namespace checks and read resources from other namespaces using the Kyverno admission controller's ServiceAccount credentials.
