Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The RabbitMQ Java client (com.rabbitmq:amqp-client, Maven) versions before 5.33.1 are vulnerable to a denial of service caused by unbounded recursion when parsing nested tables and arrays. A malicious AMQP server or man-in-the-middle can send a deeply nested structure, causing a StackOverflowError that kills the client I/O thread. Upgrade to amqp-client 5.33.1 or later.
