CVE-2026-6857Network attack vectorHinoki check available

Authenticated code execution via unfiltered Java deserialization

Published Apr 22, 2026 · Updated Sep 14, 2026

Unsafe deserialization in the camel-infinispan component allows remote authenticated users to execute arbitrary code. DefaultExchangeHolderUtils.deserialize() passes repository bytes to ClassLoadingAwareObjectInputStream.readObject() without an ObjectInputFilter. Exploitation requires low-privileged access to a deployment configured for ProtoStream remote aggregation and grants control of the affected process.
