CVE-2026-71194

A flaw was found in the OpenStack Designate mDNS NOTIFY handler. The handlenotify method performs zone lookups without poolid scoping, unlike the QUERY and AXFR handlers which were previously updated to be pool-aware. When zones with the same name exist across different DNS pools, the storage lay...

CVE-2026-71193

A flaw was found in OpenStack Designate. When the AttributeFilter scheduler is enabled with multiple DNS pools, an authenticated tenant can bypass zone ownership checks by scheduling a zone to a different pool. The database uniqueness constraint on zone names is pool-scoped, and the...

EUVD-2026-57689

In OpenStack Designate before 22.0.1, zone creation checks issubzone, issuperzone, and the duplicate-zone DB constraint are scoped to the target pool only. An authenticated user can bypass these checks by scheduling a zone to a different pool via the AttributeFilter scheduler, creating an...

EUVD-2026-57692

In OpenStack Designate before 22.0.2, the mDNS handler performs pool-blind lookups when resolving record queries and NOTIFY requests. When two zones with the same name exist across different pools, the lookup fails with a deterministic error, causing the handler to return REFUSED for all DNS...
