Machine-written summary

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

RabbitMQ amqp091-go versions before 1.13.0 are vulnerable. A malicious or compromised AMQP server can send a frame with a crafted byte-array field length that causes an unrecovered runtime panic, crashing the client process. No fix is listed other than upgrading to 1.13.0, which is the fixed version.
