How to fix?

There is no fixed version for Minimos:latest calico-3.29-typha-client.

NVD Description

Note: Versions mentioned in the description apply only to the upstream calico-3.29-typha-client package and not the calico-3.29-typha-client package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.
