{“lastseen”:””,”description”:”Improper Input Validation, Improper Control of Generation of Code (‘Code Injection’) vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ.\\n\\n\\n\\nAn authenticated attacker may bypass the fix in CVE-2026-34197 by adding a connector using an HTTP Discovery transport via\u00a0BrokerView.addNetworkConnector or\u00a0BrokerView.addConnector through\u00a0Jolokia if the activemq-http module is on the classpath.\\nA malicious HTTP endpoint can return a VM transport through the HTTP URI which will bypass the validation added in CVE-2026-34197. The attacker can then use 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\\nThis issue affects Apache ActiveMQ Broker: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ All: before 5.19.6, from 6.0.0 before 6.2.5; Apache ActiveMQ: before 5.19.6, from 6.0.0 before 6.2.5.\\n\\nUsers are recommended to upgrade to version 5.19.6 or 6.2.5, which fixes the issue.”,”published”:”2026-04-24T10:15:44.445Z”,”modified”:”2026-04-24T18:17:21.178Z”,”type”:”cve”,”title”:”Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ: Possible bypass of CVE-2026-34197 via HTTP discovery second-stage URI”,”source”:”apache”,”references”:”https:\/\/activemq.apache.org\/security-advisories.data\/CVE-2026-34197-announcement.txt”,”id”:”CVE-2026-40466″,”bulletinFamily”:””,”cwe”:[“CWE-20″,”CWE-94″],”cvelist”:null,”sourceData”:”Apache Software Foundation Apache ActiveMQ Broker 0\\nApache Software Foundation Apache ActiveMQ Broker 6.0.0\\nApache Software Foundation Apache ActiveMQ All 0\\nApache Software Foundation Apache ActiveMQ All 6.0.0\\nApache Software Foundation Apache ActiveMQ 0\\nApache Software Foundation Apache ActiveMQ 6.0.0″,”sourceHref”:””,”cvss”:{“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”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”Apache ActiveMQ Broker”,”version”:”0″,”vendor”:”Apache Software Foundation”,”ai_description”:”Arbitrary code execution via improper input validation and code injection in Apache ActiveMQ Broker, All, and Apache ActiveMQ”,”ai_severity”:”High”,”ai_vendor”:”Apache Software Foundation”,”ai_product”:”Apache ActiveMQ”,”ai_version”:”before 5.19.6, from 6.0.0 before 6.2.5″,”ai_score”:8.8}<\/p>\n","protected":false},"excerpt":{"rendered":"
