Published Sep 16, 2026 · Updated Sep 17, 2026 · Assigned by WPScan

Description

The Visualizer WordPress plugin before 4.0.8 does not sanitise and escape a chart's JSON data source configuration before outputting it back in the chart editor, allowing users with the Contributor role and above to store JavaScript that executes in the browser of any higher-privileged user, such as an administrator, who reviews the affected chart.
