| Doc Text: |
A flaw was found in Highcharts. This vulnerability allows cross-site scripting (XSS) because the library applies breadcrumb styling as unfiltered Scalable Vector Graphics (SVG) attributes rather than style properties. A remote attacker who controls chart configurations can inject malicious event handlers into breadcrumb navigation settings. When a user interacts with the affected breadcrumb button, the script executes within the context of the victim's browser session, potentially enabling unauthorized actions or data exposure.
