CVE-2026-45505: Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ: Jolokia `addNetworkConnector` Discovery Wrapper Bypass

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.60% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Apache Software Foundation Apache ActiveMQ 5.19.7, 6.2.6; Apache Software Foundation Apache ActiveMQ All 5.19.7, 6.2.6; Apache Software Foundation Apache ActiveMQ Broker 5.19.7, 6.2.6.

Low priority for now. Upgrade to Apache Software Foundation Apache ActiveMQ 5.19.7, 6.2.6; Apache Software Foundation Apache ActiveMQ All 5.19.7, 6.2.6; Apache Software Foundation Apache ActiveMQ Broker 5.19.7, 6.2.6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
