CVE-2026-86404: Deserialization of Untrusted Data in Red Hat Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7CVE-2026-86404 0 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. Join the discussion | CVE Database V5 | 09/07/2026, 11:35:04 UTC Added: 09/07/2026, 11:53:45 UTC |
