The operator reads the OpenShift Service CA private signing key from the openshift-service-ca namespace and uses it to mint client certificates with a Subject Common Name (CN) supplied by the author of a namespaced Hawtio custom resource. Because the operator ships a ClusterRole that aggregates Hawtio CR permissions into the edit and admin roles, any user with edit access in any namespace can obtain a Service-CA-signed certificate with an arbitrary subject. This certificate can be used to impersonate any in-cluster service identity to peers that trust the Service CA for client authentication, including Jolokia agents and other Service-CA-trusting components.","published":"2026-09-08T12:16:59.560","modified":"2026-09-08T12:16:59.560","cvss":{"score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-78234"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2524894"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-08T12:16:59.560"}}
