    Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 8 · Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 9 · Red Hat JBoss Enterprise Application Platform 8.1.8.GA · Red Hat JBoss Enterprise Application Platform 8.1 for RHEL 10

    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.
