Quick assessment
Affected
Apache Software Foundation Apache ActiveMQ Broker
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Apache ActiveMQ是美国阿帕奇（Apache）基金会的一套开源的消息中间件，它支持Java消息服务、集群、Spring Framework等。 Apache ActiveMQ存在安全漏洞，该漏洞源于输入验证不当和代码生成控制不当，可能导致已认证攻击者通过特制发现URI触发VM传输的brokerConfig参数加载远程Spring XML应用上下文，从而在代理JVM上执行任意代码。以下版本受到影响：Apache ActiveMQ Broker 5.19.7之前版本和6.0.0版本至6.2.6之前

Vulnerability Title
Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ: Jolokia `addNetworkConnector` Discovery Wrapper Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ.
Non-parenthesized discovery wrappers such as `masterslave:vm://...,...`
and `static:vm://...` incorrectly pass validation allowing bypass of fix in CVE-2026-34197.
Original description from CVE-2026-34197.
Apache ActiveMQ exposes the Jolokia JMX-HTTP bridge at /api/jolokia/ on the web console. The default Jolokia access policy permits exec operations on all ActiveMQ MBeans (org.apache.activemq:*), including BrokerService.addNetworkConnector(String) and BrokerService.addConnector(String). An authenticated attacker can invoke these operations with a crafted discovery UR that triggers 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 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ All: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ: before 5.19.7, from 6.0.0 before 6.2.6.
Users are recommended to upgrade to version 5.19.7 or 6.2.6, which fixes the issue.
