Archana, I believe the right place to open this bug is at https://github.com/rabbitmq/rabbitmq-server/issues/new as the logs mentioned here has nothing to do with Keystone.

If this behavior is configurable or other mitigation can be devised, or if it gets patched upstream in rabbitmq, then a security note (not advisory) may be appropriate to let operators know about the risk and what they can do.

This likely is more related to RabbitMQ (and as fungi pointed out, should probably be noted in OSSN) if it has a security impact on OpenStack as a whole, rather than specifically keystone.
