The default Jolokia access policy permits exec operations on all ActiveMQ MBeans (org.apache.activemq:*), including\nBrokerService.addNetworkConnector(String) and BrokerService.addConnector(String).\n\nAn authenticated attacker can invoke these operations with a crafted discovery URI that triggers the VM transport's brokerConfig parameter to load a remote Spring XML application context using ResourceXmlApplicationContext.\nBecause 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().\n\n\n\nThis issue affects Apache ActiveMQ Broker: before 5.19.4, from 6.0.0 before 6.2.3; Apache ActiveMQ All: before 5.19.4, from 6.0.0 before 6.2.3; Apache ActiveMQ: before 5.19.4, from 6.0.0 before 6.2.3.\n\n\n\nUsers are recommended to upgrade to version 5.19.4 or 6.2.3, which fixes the issue","published":"2026-04-07T09:16:21.000Z","lastModified":"2026-10-26T22:10:00.000Z","status":"Analyzed","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-20","CWE-94","CWE-78"],"affected":["apache/activemq","apache/activemq broker"],"epss":{"score":0.98256,"percentile":0.99916,"date":"2026-10-30","history":[{"date":"2026-09-24","score":0.15492,"percentile":0.96683},{"date":"2026-10-25","score":0.98256,"percentile":0.99915}]},"kev":{"listed":true,"dateAdded":"2026-04-16","dueDate":"2026-04-30","knownRansomwareCampaignUse":"Unknown","notes":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.\nhttps://activemq.apache.org/security-advisories.data/CVE-2026-34197-announcement.txt ; https://nvd.nist.gov/vuln/detail/CVE-2026-34197"},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 30 April 2026).
