Description

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.

Affected configurations

• tigera calico (< 3.21.7) • tigera calico (< 3.31.6) • tigera calico (<= 22.4.0) • tigera calico (>= 3.22.0 < 3.22.4) • tigera calico (>= 3.32.0 < 3.32.1)
