A flaw was found in the Pen Drive report generator. Cluster-sourced data is rendered into HTML reports without proper escaping or sanitization. An attacker with cluster administrator privileges can inject a stored cross-site scripting (XSS) payload into cluster objects (such as ClusterVersion spec.channel) that executes in the browser of any user who opens the generated HTML report.
