RabbitMQ is a messaging and streaming broker. Prior to 4.2.6, RabbitMQ AMQP 0-9-1 allows an existing consumer to keep receiving messages after OAuth token expiry or connection.update_secret refresh to reduced scopes because existing consumers are not canceled or reauthorized at delivery time after the channel user state changes. This issue is fixed in version 4.2.6.
A flaw was found in RabbitMQ. An existing consumer in RabbitMQ AMQP 0-9-1 can continue to receive messages even after its OAuth token has expired or its connection's scopes have been reduced. This occurs because consumers are not properly canceled or reauthorized when the channel user state changes, potentially leading to unauthorized information disclosure.
