Apache Artemis, Apache ActiveMQ Artemis: Pre-Authentication Information Disclosure in CORE Protocol Topology Subscription
An unauthenticated remote attacker connecting with the CORE protocol can discover cluster node details by sending a SUBSCRIBE_TOPOLOGY request prior to authentication.
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.
