CVE-2026-118246

8.4 high Published
NVD · CVE.org

Highcharts JS is a JavaScript charting library based on SVG. From 10.0.0 until 11.4.9, 12.6.1, and 13.1.0, Highcharts applies breadcrumbs.style as SVG attributes rather than CSS and does not filter the attribute names. An attacker who controls chart configuration can provide event-handler keys through drilldown.breadcrumbs, navigation.breadcrumbs, or hierarchical series breadcrumb options. The keys become active handlers on the breadcrumb button and execute in the hosting page origin after the user navigates to a level and hovers over or activates the button. Styled-mode charts do not apply this option and are not affected. This issue is fixed in 11.4.9, 12.6.1 and 13.1.0.

Fix
