CVSS 8.8 · High EPSS 0,86%
Kerentanan Deserialization of Untrusted Data. Skor CVSS 3.1 8.8 (High) menurut redhat.com.
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.
