CVE-2026-57822: Deserialization of Untrusted Data

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...

CVE-2026-49364: Missing Authentication for Critical Function

An unauthenticated network-adjacent attacker can leverage discovery to capture cluster administrative credentials during the initial cluster connection handshake. 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 recommend...

CVE-2026-75880: Inefficient Regular Expression Complexity

An authenticated client could attach a consumer with a selector containing crafted wildcard usage that results in excessive evaluation during message delivery attempts, occupying a shared broker thread and leading to denial of service. This issue affects Apache Artemis: from 2.50.0 through 2.56.0...

CVE-2026-49363: Missing Authentication for Critical Function

An unauthenticated remote attacker connecting with the CORE protocol can discover cluster node details by sending a SUBSCRIBETOPOLOGY 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...
