A fix is available — apply it.

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 () and no-argument constructors (()) 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.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (CISA Vulnrichment) · Automatable yes (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
