Threats affecting pkg:github/ekacnet/grafanacubism-panel

CVE-2026-32117 is a high-severity cross-site scripting (XSS) vulnerability in the ekacnet grafanacubism-panel plugin for Grafana versions 0.1.2 and earlier. The flaw arises because the panel’s zoom-link handler directly passes a dashboard editor-supplied URL to window.location.assign() or window.open() without validating the URL scheme. An attacker with dashboard editor privileges can inject a javascript: URI, which executes malicious code in the context of the Grafana origin when any viewer performs a drag-zoom action on the panel. This vulnerability requires at least editor-level privileges and user interaction but can lead to high confidentiality impact by stealing session tokens or performing actions on behalf of the user. No known exploits are currently reported in the wild.
