Any user with the default create_zone policy can exploit this when the AttributeFilter scheduler is enabled. Only deployments using the AttributeFilter scheduler with multiple pools are affected. - The mDNS handler performs pool-blind record lookups that fail when colliding zones exist across pools, causing deterministic DNS query failures. The NOTIFY handler path is reachable via unauthenticated UDP. Applied upstream patches: - Require TSIG keys for zones in non-default pools - Fix mDNS record query pool scoping for split-horizon DNS - Fix cross-tenant/cross-pool zone ownership bypass (Closes: #1144145).
