An unauthenticated remote attacker can create arbitrary durable queues via the CORE protocol, leading to unauthorized broker state manipulation and potential denial of service. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue.

An unauthenticated remote attacker can create arbitrary durable queues via the CORE protocol, leading to unauthorized broker state manipulation and potential denial of service. This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.0.0 through 2.44.0. Users are recommended to upgrade to version 2.57.0, which fixes the issue.
