Highcharts JS is a JavaScript charting library based on SVG. From 2.0.0 until 3.2.0, Highcharts Grid applies credits.href to the credits link without validating the URL scheme. An attacker who controls Grid configuration can provide a javascript URL, and activating the credits link runs script in the origin of the hosting page with access to that application's data and session state.This issue is fixed in Grid Pro 3.2.0.
