The method calls Class.forName(clazz).getConstructor().newInstance() where clazz is read directly from the CORE protocol wire buffer without type validation. An authenticated federation peer can send a FEDERATION_DOWNSTREAM_CONNECT packet with a crafted class name, causing the broker to load and instantiate arbitrary classes visible to the Artemis module classloader. Static initializers (<clinit>) and no-argument constructors (<init>()) execute as side effects before the type cast, enabling denial of service via system-property poisoning, out-of-memory conditions via classloading, or broker state manipulation."}],"affected":[{"vendor":"Red Hat","product":"Red Hat JBoss Enterprise Application Platform 7.4.25","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"org.apache.activemq/artemis-core-client","defaultStatus":"affected","versions":[{"version":"2.16.0.redhat-00057","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:jboss_enterprise_application_platform:7.4"]},{"vendor":"Red Hat","product":"Red Hat AMQ Broker 7","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"artemis-core-client","defaultStatus":"unaffected","cpes":["cpe:/a:redhat:amq_broker:7"]},{"vendor":"Red Hat","product":"Red Hat JBoss Enterprise Application Platform 7","collectionURL":"https://access.redhat.com/jbossnetwork/restricted/listSoftware.html","packageName":"artemis-core-client","defaultStatus":"affected","cpes":["cpe:/a:redhat:jboss_enterprise_application_platform:7"]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:53644","name":"RHSA-2026:53644","tags":["technical-description","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:53806","name":"RHSA-2026:53806","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-101292","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2482963","name":"RHBZ#2482963","tags":["issue-tracking","x_refsource_REDHAT"]}],"datePublic":"2026-08-11T05:51:26.659Z","problemTypes":[{"descriptions":[{"cweId":"CWE-470","description":"Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection')","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-470: Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection')","timeline":[{"lang":"en","time":"2026-05-28T21:41:41.272Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-08-11T05:51:26.659Z","value":"Made public."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-09-29T15:57:31.561Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-28T13:10:25.501009Z","id":"CVE-2026-101292","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-28T13:10:33.668Z"}}]}}
