DescriptionNVD
Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ.
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. 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's brokerConfig parameter to load a remote Spring XML application context using ResourceXmlApplicationContext. Because Spring's ResourceXmlApplicationContext instantiates all singleton beans before the BrokerService validates the configuration, arbitrary code execution occurs on the broker's JVM through bean factory methods such as Runtime.exec().
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.
Users are recommended to upgrade to version 5.19.6 or 6.2.5, which fixes the issue.
AnalysisAI
Remote code execution in Apache ActiveMQ 5.x (before 5.19.6) and 6.x (before 6.2.5) allows authenticated attackers to bypass prior security fixes (CVE-2026-34197) by injecting malicious Spring XML configurations through HTTP Discovery transport connectors via Jolokia. Attackers leverage a VM transport loophole to invoke arbitrary bean factory methods like Runtime.exec() during Spring context initialization. …

RemediationAI
Within 24 hours: Identify all ActiveMQ deployments running versions 5.x or 6.x and verify activemq-http module presence; document current versions and Jolokia exposure. Within 7 days: Apply vendor-released patches (ActiveMQ 5.19.6 or later for 5.x; 6.2.5 or later for 6.x) to all affected instances; restart services and verify successful upgrade. …
