Highcharts JS is a JavaScript charting library based on SVG.
Highcharts JS is a JavaScript charting library based on SVG. From 1.0.0 until 4.2.3, Highcharts Dashboards edit-mode sidebar parses component language strings as HTML rather than inserting them as text. An attacker who controls the Dashboards language configuration can provide markup containing event handlers, which execute in the hosting page origin when a user opens the edit-mode sidebar and the affected labels render. This issue is fixed in 4.2.3.
