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."}], "affected": [{"vendor": "Red Hat", "product": "Red Hat build of Apache Camel - HawtIO 4", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "rhbac-4/hawtio-gateway-rhel9", "defaultStatus": "affected", "cpes": ["cpe:/a:redhat:apache_camel_hawtio:4"]}, {"vendor": "Red Hat", "product": "Red Hat build of Apache Camel - HawtIO 4", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "rhbac-4/hawtio-operator-bundle", "defaultStatus": "affected", "cpes": ["cpe:/a:redhat:apache_camel_hawtio:4"]}, {"vendor": "Red Hat", "product": "Red Hat build of Apache Camel - HawtIO 4", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "rhbac-4/hawtio-rhel9", "defaultStatus": "affected", "cpes": ["cpe:/a:redhat:apache_camel_hawtio:4"]}], "references": [{"url": "https://access.redhat.com/security/cve/CVE-2026-78234", "tags": ["vdb-entry", "x_refsource_REDHAT"]}, {"url": "https://bugzilla.redhat.com/show_bug.cgi?id=2524894", "name": "RHBZ#2524894", "tags": ["issue-tracking", "x_refsource_REDHAT"]}], "datePublic": "2026-09-08T10:55:10.366Z", "problemTypes": [{"descriptions": [{"cweId": "CWE-295", "description": "Improper Certificate Validation", "lang": "en", "type": "CWE"}]}], "x_redhatCweChain": "CWE-295: Improper Certificate Validation", "workarounds": [{"lang": "en", "value": "Do not set spec.routeHostName to values outside the operator's own namespace service names.
