Mitigation checklist
- To mitigate this issue, ensure that all AMQP client connections are configured to use TLS with certificate validation. This prevents on-path attackers from exploiting the vulnerability by ensuring the authenticity of the AMQP server and encrypting traffic. Proper certificate management and configuration are required on both the client and server sides. Restart any services utilizing `rabbitmq-c` after applying this configuration change for it to take effect.
