Options structure open to Cross-site Scripting if passed unfiltered
Impact
In Highcharts versions 8 and earlier, the chart options structure was not systematically filtered for XSS vectors. The potential impact was that content from untrusted sources could execute code in the end user's browser. Especially when using the useHTML flag, HTML string options would be inserted unfiltered directly into the DOM. When useHTML was false, malicious code could be inserted by using various character replacement tricks or malformed HTML.
If your chart configuration comes from a trusted source like a static setup or pre-filtered HTML (or no markup at all in the configuration), you are not impacted.
Patches
In version 9, the whole rendering layer was refactored to use an DOMParser, an AST and tag and HTML allow-listing to make sure only safe content entered the DOM. In addition, prototype pollution was stopped.
Workarounds
Implementers who are not able to upgrade may apply DOMPurify recursively to the options structure to filter out malicious markup.
