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","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-20","CWE-94","CWE-78"],"references":["https://activemq.apache.org/security-advisories.data/CVE-2026-34197-announcement.txt","http://www.openwall.com/lists/oss-security/2026/04/06/3","https://access.redhat.com/security/cve/CVE-2026-34197","https://bugzilla.redhat.com/show_bug.cgi?id=2455869","https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-34197.json"],"products":["apache:activemq","apache:activemq_broker"],"source":"nvd","synced_at":"2026-10-26T22:26:44.656832877+00:00"},"epss":{"cve":"CVE-2026-34197","score":0.98256,"percentile":0.99915,"date":"2026-10-26"},"kev":{"cve":"CVE-2026-34197","date_added":"2026-04-16","due_date":"2026-04-30","vendor":"Apache","product":"ActiveMQ","known_ransomware":false},"osv":[{"id":"GHSA-rxpj-7qvf-xv32","url":"https://osv.dev/vulnerability/GHSA-rxpj-7qvf-xv32","summary":"Authenticated Apache ActiveMQ Broker and Apache ActiveMQ users could perform RCE via Jolokia MBeans","modified":"2026-09-10T03:50:44.927548510Z","packages":[{"ecosystem":"Maven","name":"org.apache.activemq:activemq-broker","purl":"pkg:maven/org.apache.activemq/activemq-broker","ranges":["<5.19.5"],"fixed":["5.19.5"]},{"ecosystem":"Maven","name":"org.apache.activemq:activemq-broker","purl":"pkg:maven/org.apache.activemq/activemq-broker","ranges":[">=6.0.0 <6.2.3"],"fixed":["6.2.3"]},{"ecosystem":"Maven","name":"org.apache.activemq:activemq-all","purl":"pkg:maven/org.apache.activemq/activemq-all","ranges":["<5.19.5"],"fixed":["5.19.5"]},{"ecosystem":"Maven","name":"org.apache.activemq:activemq-all","purl":"pkg:maven/org.apache.activemq/activemq-all","ranges":[">=6.0.0 <6.2.3"],"fixed":["6.2.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
