How to fix?

Upgrade org.apache.kafka:kafka-clients to version 2.1.1 or higher.

Overview

org.apache.kafka:kafka-clients is a streaming platform that can publish and subscribe to streams of records, store streams of records in a fault-tolerant durable way, and process streams of records as they occur.

Affected versions of this package are vulnerable to Access Restriction Bypass. It is possible to manually craft a Produce request which bypasses transaction/idempotent ACL validation. Only authenticated clients with Write permission on the respective topics are able to exploit this vulnerability.
