When the broker is processing message-based management requests, sent by an authenticated messaging client that is authorized with MANAGE permission to perform management-via-messaging, the parameter processing can trigger Java deserialization of certain method parameters that the broker will not utilise. The permitted types allow to craft a payload causing excessive computation and pinning the processing thread, leading to denial of service.
This issue affects Apache Artemis: from 2.50.0 through 2.56.0; Apache ActiveMQ Artemis: from 1.3.0 through 2.44.0.
Users are recommended to upgrade to version 2.57.0, which fixes the issue.
