To exploit this vulnerability, the attacker needs to be able to connect to the Kafka cluster and have the AlterConfigs permission on the cluster resource.\n\n\nSince Apache Kafka 3.4.0, we have added a system property (\"-Dorg.apache.kafka.disallowed.login.modules\") to disable the problematic login modules usage in SASL JAAS configuration.
