## Technical details

A pre-authentication StackOverflowError vulnerability exists in Apache Qpid Broker-J's type parsing logic when processing deeply nested type structures. An unauthenticated network attacker can trigger this by sending malformed AMQP protocol messages that exploit recursive type nesting, causing the Java stack to overflow and crash the broker process. The issue is resolved in version 10.1.1.
