CVE-2026-40466

*** Pendiente de traducción *** Improper Input Validation, Improper Control of Generation of Code (&amp;#39;Code Injection&amp;#39;) vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ.<br /> <br /> <br /> <br /> An authenticated attacker may bypass the fix in CVE-2026-34197 by adding a connector using an HTTP Discovery transport via BrokerView.addNetworkConnector or BrokerView.addConnector through Jolokia if the activemq-http module is on the classpath.<br /> A malicious HTTP endpoint can return a VM transport through the HTTP URI which will bypass the validation added in CVE-2026-34197. The attacker can then use the VM transport&amp;#39;s brokerConfig parameter to load a remote Spring XML application context using ResourceXmlApplicationContext.<br /> Because Spring&amp;#39;s ResourceXmlApplicationContext instantiates all singleton beans before the BrokerService validates the configuration, arbitrary code execution occurs on the broker&amp;#39;s JVM through bean factory methods such as Runtime.exec().<br /> <br /> <br /> This issue affects Apache ActiveMQ Broker: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ All: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ: before 5.19.6, from 6.0.0 before 6.2.5.<br /> <br /> Users are recommended to upgrade to version 5.19.6 or 6.2.5, which fixes the issue.
