Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-40466 exists.\n\nAffected packages and fixed versions:\n- org.apache.activemq:activemq-all (Maven): affected all versions; fixed in 5.19.6\n- org.apache.activemq:activemq-all (Maven): affected all versions; fixed in 5.19.6\n- org.apache.activemq:activemq-all (Maven): affected from 6.0.0; fixed in 6.2.5\n- org.apache.activemq:activemq-all (Maven): affected from 6.0.0; fixed in 6.2.5\n- activemq (Bitnami): affected all versions; fixed in 5.19.6, 6.2.5\n- org.apache.activemq:activemq-broker (Maven): affected all versions; fixed in 5.19.6\n- org.apache.activemq:activemq-broker (Maven): affected all versions; fixed in 5.19.6\n- org.apache.activemq:activemq-broker (Maven): affected from 6.0.0; fixed in 6.2.5\n- org.apache.activemq:activemq-broker (Maven): affected from 6.0.0; fixed in 6.2.5\n- org.apache.activemq:apache-activemq (Maven): affected all versions; fixed in 5.19.6\n- org.apache.activemq:apache-activemq (Maven): affected all versions; fixed in 5.19.6\n- org.apache.activemq:apache-activemq (Maven): affected from 6.0.0; fixed in 6.2.5\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-40466/ (Markdown: https://insights.sbomify.com/CVE-2026-40466/index.md)","id":"CVE-2026-40466","markdown":"https://insights.sbomify.com/CVE-2026-40466/index.md","name":"CVE-2026-40466","record":{"aliases":["BIT-activemq-2026-40466","DEBIAN-CVE-2026-40466","GHSA-w3w2-mpp5-92gm","MINI-5q94-4cm7-4j2v","MINI-cqqg-h2pg-fjf6","MINI-frhq-vww8-c28v","MINI-x9j5-jh9p-j9v4","ROOT-APP-MAVEN-CVE-2026-40466","UBUNTU-CVE-2026-40466"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache ActiveMQ Broker","requires_auth":"low_privilege","summary":"Authenticated attackers can achieve remote code execution on Apache ActiveMQ brokers by bypassing input validation via HTTP discovery transport.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"activemq","vendor":"apache"},{"product":"activemq_broker","vendor":"apache"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper Input Validation, Improper Control of Generation of Code ('Code Injection') vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ.\n\nAn authenticated attacker may bypass the fix in CVE-2026-34197 by adding a connector using an HTTP Discovery transport via BrokerView.addNetworkConnector or BrokerView.addConnector through Jolokia 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\nThis
