CVE-2026-86404
Artemis-server: artemis-jms-client: artemis-core-client: undertow-core: wildfly-messaging-activemq-subsystem: artemis messaging handlers in red hat eap permit deserialization by default

EAP's Artemis deserialization configuration permits deserialization by default. ObjectMessage.getObject() uses ObjectInputStreamWithClassLoader, which implements allow-list/block-list filtering via its checkSecurity()/isTrustedType() method. However, by default both allow-list and block-list are empty. When the allow-list is empty (size == 0), isTrustedType() returns true for ALL classes. This means all classes are deserializable by default.
