CVE-2026-45505 (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 over the /api/jolokia MBeans interface. A user can execute arbitrary code on the broker's JVM by invoking operations with a malicious discovery URI that feeds into the VM transport's brokerConfig parameter that causes the loading of a remote Spring XML application context using ResourceXmlApplicationContext. This allows for the instantiation of malicious beans through factory methods such as Runtime.exec().
