{"schema":"threatline.record/2","record":{"id":"CVE-2026-101292","aliases":[],"summary":"Artemis-core-client: unsafe reflection in apache activemq artemis federation message deserialization","details":"Apache ActiveMQ Artemis before 2.34.0 contains an unsafe reflection vulnerability in FederationStreamConnectMessage.getFederationPolicy(). 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.","categories":["Operating systems"],"product":"Red Hat JBoss Enterprise Application Platform 7.4.25","vendor":"Red
