CVE-2026-78234Network attack vector

Service impersonation via attacker-chosen certificate subjects

Published Sep 8, 2026 · Updated Sep 8, 2026

Certificate-signing abuse in Red Hat build of Apache Camel - HawtIO 4 allows remote authenticated users to impersonate services via a Hawtio CR. The hawtio-operator reads the OpenShift Service CA private key and signs client certificates whose Common Name comes directly from a namespaced Hawtio custom resource. Namespace edit access is sufficient; a forged identity can cross tenant boundaries and can execute code when a trusting Jolokia agent exposes MBean invocation.
