NVD Description
Note: Versions mentioned in the description apply only to the upstream eap7-ironjacamar-core-api package and not the eap7-ironjacamar-core-api package as distributed by RHEL.
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.
