Incorrect access control in the Kafka Connect REST API in the STRIMZI Project 0.41.0 and earlier allows an attacker to deny the service for Kafka Mirroring, potentially mirror the topics' content to his Kafka cluster via a malicious connector (bypassing Kafka ACL if it exists), and potentially steal Kafka SASL credentials, by querying the MirrorMaker Kafka REST API.
