CVE-2026-78234 (GCVE-0-2026-78234)

Vulnerability from cvelistv5 – Published: 2026-09-08 11:27 – Updated: 2026-09-08 12:19

Title

Hawtio-operator: hawtio-operator: service-ca signing oracle allows arbitrary-cn certificate issuance to namespace edit users

Summary

A flaw was found in hawtio-operator. 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.

  "details": "A flaw was found in hawtio-operator. 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.",
