Severity

8.4 (High) CVSS_V4 - CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:N/SC:L/SI:L/SA:N CVSS Calculator

Summary

Highcharts: `javascript:` URL in credits.href runs script on click

Details

Impact

A credits.href value beginning with javascript: is assigned to the window location when the credits label is clicked, without being checked against an allowed-scheme list. An attacker who controls the chart configuration can therefore run script in the origin of the page hosting the chart. Exploitation requires that untrusted data reach the chart configuration and that a user click the credits label. Charts built with Highcharts Stock, Maps and Gantt are included, since those ship from the same package as Core.

Workarounds

Drop-in fix - for any versions affected (5.0.0-13.0.2). Add the below IIFE to run after Highcharts is loaded, but before a chart is created.

!function(t){if(t&&t.Chart&&!t.Chart.prototype.creditsHrefPatched){var r=t.Chart.prototype,e=r.addCredits;r.addCredits=function(n){var o=t.merge(!0,this.options.credits,n);return o&&o.href&&!c(o.href)&&delete o.href,e.call(this,o)},r.creditsHrefPatched=!0}function c(r){var e=t.AST&&t.AST.allowedReferences||["https://","http://","mailto:","/","../","./","#"];return"string"==typeof r&&e.some(function(t){return 0===r.indexOf(t)})}}(Highcharts);
