What is CVE-2026-86404?

The Artemis framework by Red Hat has a significant deserialization issue where the default configuration allows deserialization of objects without proper restrictions. The ObjectMessage.getObject() method uses ObjectInputStreamWithClassLoader, which relies on an empty allow-list and block-list for filtering. This configuration flaw results in the isTrustedType() method returning true for all classes by default, creating an exploitable vector for untrusted data deserialization.
