Описание
Calico's apiserver wraps tier-scoped resources so that every operation runs through AuthorizeTierOperation, but the Delete override on NetworkPolicy, GlobalNetworkPolicy, and their staged variants is not invoked for DeleteCollection requests. A user holding the deletecollection verb or wildcard verbs on tier-scoped policy resources can bulk-delete policies in tiers they otherwise have no rights on, breaking the tier authorization boundary.
