Technical details

The vulnerability is a property injection flaw in the HighchartsComponent.createChart() method, where the chartConstructor parameter is used directly as an unchecked object property lookup against the Highcharts namespace without validation. An attacker can specify a public utility function instead of a supported chart type, and when invoked with the component container and chartOptions, attacker-controlled options are copied as properties or attributes on the DOM container, enabling markup injection and arbitrary event handler execution within the hosting page's origin.

Affected products
