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) versions before 5.18.0 do not apply the configured maximum body length when receiving messages. An attacker who can send a very large message to a queue a consumer reads from can exhaust that consumer's memory and cause an OutOfMemoryError. Upgrade to amqp-client 5.18.0 or later. The source gives few details on other workarounds.
