A flaw was found in apache-kafka. This issue occurs due to improper handling of configuration data when using a Kafka client SASL JAAS, allowing an attacker with access to alterConfig for a cluster resource or Kafka Connect worker to inject arbitrary configuration. This injection can lead to the creation or modification of connectors with malicious configurations. Consequently, this can allow an attacker to compromise the integrity and availability of the Kafka cluster or Kafka Connect worker.
