Official description

The grafanacubism-panel plugin allows use of cubism.js in Grafana. In 0.1.2 and earlier, the panel's zoom-link handler passes a dashboard-editor-supplied URL directly to window.location.assign() / window.open() with no scheme validation. An attacker with dashboard Editor privileges can set the link to a javascript: URI; when any Viewer drag-zooms on the panel, the payload executes in the Grafana origin.
