Vulnerability identifier: #VU125787
Vulnerability risk: Medium
CVSSv4.0: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Green
CVE-ID: CVE-2026-34197
CWE-ID: CWE-94
Exploitation vector: Remote access
Exploit availability: The vulnerability is being exploited in the wild
Vulnerable software:
ActiveMQ
Software vendor:
Apache Foundation

Description

The vulnerability allows a remote user to execute arbitrary code.

The vulnerability exists due to code injection in the Jolokia JMX-HTTP bridge and exposed ActiveMQ MBeans when handling authenticated exec operations with a crafted discovery URI. A remote user can invoke BrokerService.addNetworkConnector(String) or BrokerService.addConnector(String) to execute arbitrary code.

The issue is exposed through the web console endpoint at /api/jolokia/, and exploitation causes remote Spring XML application context loading via the VM transport's brokerConfig parameter before configuration validation completes.
