NVD Description

Note: Versions mentioned in the description apply only to the upstream rabbitmq-server4.2 package and not the rabbitmq-server4.2 package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

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.
