CVE-2026-118245Highcharts Dashboards: `chartConstructor` is an unchecked lookup into the Highcharts namespace

Açıklama

Highcharts JS is a JavaScript charting library based on SVG. From 1.0.0 until 4.2.2, Highcharts Dashboards uses chartConstructor as an unchecked property lookup in the Highcharts namespace and invokes the selected member with the component container and chartOptions. An attacker who controls dashboard configuration can select a public utility function instead of a supported chart constructor, causing attacker-controlled options to be copied to the container as properties or attributes. Markup and event handlers can then execute in the hosting page origin when the board renders. No user interaction beyond rendering the board is required. This issue is fixed in 4.2.2.
