CVE-2026-42588 (opens in a new tab)How to fix?
Upgrade org.apache.activemq:activemq-broker to version 5.19.7, 6.2.6 or higher.
Overview
org.apache.activemq:activemq-broker is a high performance Apache 2.0 licensed Message Broker and JMS 1.1 implementation.
Affected versions of this package are vulnerable to Improper Input Validation through the addNetworkConnector function exposed via the Jolokia JMX-HTTP bridge. An attacker can achieve arbitrary code execution by invoking MBean operations with a crafted discovery URI that leverages the VM transport's brokerConfig parameter, resulting in the loading of a malicious Spring XML application context. This leads to the instantiation of attacker-controlled beans before configuration validation, allowing execution of arbitrary commands on the broker's JVM.
