Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-42588 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.activemq:activemq-all (Maven): affected all versions; fixed in 5.19.7\n- org.apache.activemq:activemq-all (Maven): affected all versions; fixed in 5.19.7\n- org.apache.activemq:activemq-all (Maven): affected from 6.0.0; fixed in 6.2.6\n- org.apache.activemq:activemq-all (Maven): affected from 6.0.0; fixed in 6.2.6\n- activemq (Bitnami): affected all versions; fixed in 5.19.7, 6.2.6\n- org.apache.activemq:activemq-broker (Maven): affected all versions; fixed in 5.19.7\n- org.apache.activemq:activemq-broker (Maven): affected all versions; fixed in 5.19.7\n- org.apache.activemq:activemq-broker (Maven): affected from 6.0.0; fixed in 6.2.6\n- org.apache.activemq:activemq-broker (Maven): affected from 6.0.0; fixed in 6.2.6\n- org.apache.activemq:apache-activemq (Maven): affected all versions; fixed in 5.19.7\n- org.apache.activemq:apache-activemq (Maven): affected all versions; fixed in 5.19.7\n- org.apache.activemq:apache-activemq (Maven): affected from 6.0.0; fixed in 6.2.6\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-2026-42588/ (Markdown: https://insights.sbomify.com/CVE-2026-42588/index.md)","id":"CVE-2026-42588","markdown":"https://insights.sbomify.com/CVE-2026-42588/index.md","name":"CVE-2026-42588","record":{"aliases":["BIT-activemq-2026-42588","DEBIAN-CVE-2026-42588","GHSA-hg6c-8mvr-jqc9","MINI-3445-g9vq-rg27","MINI-4x32-cwgf-7xqp","MINI-hj6f-cv7f-j8w5","MINI-pj2j-p6v6-p663","ROOT-APP-MAVEN-CVE-2026-42588","UBUNTU-CVE-2026-42588"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache ActiveMQ Broker","requires_auth":"low_privilege","summary":"An authenticated attacker can achieve remote code execution on the Apache ActiveMQ broker by exploiting the Jolokia JMX-HTTP bridge to load malicious Spring XML configurations.","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":8.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","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\nApache ActiveMQ Classic exposes the Jolokia JMX-HTTP bridge at /api/jolokia/ on the web console. The default Jolokia access policy permits exec operations on all ActiveMQ MBeans (org.apache.activemq:*), including\nBrokerService.addNetworkConnector(String).\n\nAn authenticated attacker can invoke these operations with a crafted discovery URI that triggers the VM transport's brokerConfig parameter using the \"masterslave:// \" URL which can allow loading a 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().\nThis issue affects Apache ActiveMQ Broker: before 5.19.7, from 6.0.0 before 6.2.6; Apache ActiveMQ All: before 5.19.7, from 6.0.0
