Authenticated code execution via discovery-wrapper validation bypass
Published Jun 1, 2026 · Updated Jun 1, 2026
Code injection in Apache ActiveMQ before 5.19.7 and 6.0.0 through 6.2.5 allows remote authenticated users to execute code on the broker JVM. BrokerService.addNetworkConnector(String) and addConnector(String) accept non-parenthesized masterslave and static discovery wrappers that evade URI validation and make ResourceXmlApplicationContext instantiate attacker-controlled singleton beans before configuration validation. Reachability requires authenticated access to the Jolokia JMX-HTTP bridge and permission to execute ActiveMQ MBean operations; successful exploitation runs arbitrary code in the broker JVM.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <5.19.7
- Affected versionversion=6.0.0 <6.2.6
