| Doc Text: |
A flaw was found in Strimzi, specifically within the Kafka Connect and Kafka MirrorMaker 2 operands. When a chain of multiple Certificate Authority (CA) certificates is configured for trusted certificates, the system incorrectly trusts all certificates in the chain individually, rather than only the final CA. This vulnerability could allow an attacker to present a server certificate signed by an intermediate CA in the chain, which would be improperly accepted by the affected operand, potentially leading to a bypass of intended certificate validation and unauthorized access or information disclosure.
