CVE-2026-15555 is a deserialization vulnerability in Red Hat JBoss Enterprise Application Platform 7.4 ELS on RHEL 7. The flaw exists in the Infinispan session replication path, which deserializes session data without class filtering, allowing remote code execution via crafted deserialization payloads on cluster nodes. A security update is available in version 7.4.25 that addresses this issue.

A flaw was found in JBoss marshalling. The Infinispan session replication path deserializes replicated session data via the JBoss Marshalling River unmarshaller with no class filtering — enabling RCE via deserialization gadget chains on every cluster node.
