  "details" : [ "A flaw was found in the Apache Kafka Java producer client. A race condition in the client's buffer pool management can cause messages to be silently delivered to incorrect topics. This occurs when a message batch expires while its network request is still active, leading to premature buffer deallocation and potential reuse by other messages. Consequently, sensitive data may be exposed to unauthorized consumers, and data integrity can be compromised through deserialization failures and processing errors." ],
