Exploitation requires that untrusted data reach the chart configuration and that a user click the credits label.

With npm, upgrade the affected package to the patched version listed above, for example `npm install highcharts@ 13.1.0`. If you load Highcharts from the CDN, use the versioned URLs on code.highcharts.com, for example `https://code.highcharts.com/13.1.0/highcharts.js`.
