Mitigation checklist

Recommended fix / mitigation

To mitigate this issue, ensure that `rabbitmq-c` clients only connect to trusted AMQP servers. Additionally, enforce the use of TLS/SSL for all AMQP communication to prevent on-path attackers from exploiting this vulnerability against plaintext traffic. Consult your AMQP server and client documentation for specific configuration steps to enable and enforce TLS/SSL.
