AI-suggested
Upgrade Strimzi Kafka Operator to version 1.0.1 or later, as these versions contain fixes that properly restrict RBAC permissions of the Entity Operator ServiceAccount to only the deployed components. No other mitigation is required as the issue is resolved in these versions.
Description
Strimzi Kafka Operator versions prior to 1.0.1 have an improper privilege management vulnerability where the Entity Operator ServiceAccount retains RBAC permissions for both Topic Operator and User Operator components even when only one is deployed. This can lead to unauthorized access to KafkaUser custom resources and Secrets or KafkaTopic custom resources depending on which operator is absent. The issue is fixed in versions 1.0.1 and 1.1.0.
