CRE-2024-0043 Medium Impact: 6/10 Mitigation: 5/10	NGINX Upstream DNS Failure	When a NGINX upstream becomes unreachable or its DNS entry disappears, NGINX requests begin to fail.	Proxy Problems	nginx	Kafka Known Problem Public
CRE-2025-0025 Medium Impact: 6/10 Mitigation: 5/10	Kafka broker replication mismatch	When the configured replication factor for a Kafka topic is greater than the actual number of brokers in the cluster, Kafka repeatedly fails to assign partitions and logs replication-related errors. This results in persistent warnings or an `InvalidReplicationFactorException` when the broker tries to create internal or user-defined topics.

CRE-2025-0070 Critical Impact: 10/10 Mitigation: 6/10	Kafka Under-Replicated Partitions Crisis	Critical Kafka cluster degradation detected: Multiple partitions have lost replicas due to broker failure, resulting in an under-replicated state. This pattern indicates a broker has become unavailable, causing partition leadership changes and In-Sync Replica (ISR) shrinkage across multiple topics.
