What are the data protection (sanitization) methods in message brokers?

Question

RabbitMQ

Good afternoon, I'm interested in this question. There is a producer, consumer and a broker in the middle. The producer is in an untrusted environment, and the consumer does not know how to sanitize incoming data (assuming), and so on. the exchange protocol between them is AMQP (i.e. binary), then you can’t put WAF between them, are there any methods for checking and sanitizing data that come from the producer, except for the code on the consumer side?
