[v0.12] Validate kubeConfig Namespaces against known Fleet namespaces#5246
Merged
Conversation
Restrict kubeconfig secret reads to Fleet-managed namespaces and preserve same-namespace behavior for explicit or empty values. Keep legacy namespace entries for now because migration code paths still reference LegacyDefaultNamespace, and Rancher manager-initiated registration sets kubeConfigSecretNamespace to the cluster namespace.
