CVE-2026-86404
8.8
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.

Weaknesses
- CWE-502: Deserialization of Untrusted Data
Workarounds
Configure a restrictive deserialization-allow-list on every pooled-connection-factory resource. For example, if your MDBs only expect to receive objects of type com.yourapp.OrderEvent, set the allow-list to "com.yourapp". This switches ObjectInputStreamWithClassLoader from "allow everything" to "deny by default, allow only listed classes." With this in place, even if an attacker injects a malicious ObjectMessage through any vector, the deserialization of gadget chain classes is blocked.
