Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Highcharts (npm package highcharts) versions 10.0.0 up to 11.4.9, 12.0.0 up to 12.6.1, and 13.0.0 up to 13.1.0 are vulnerable. In these versions, keys supplied through the breadcrumbs style option are applied as unfiltered SVG attributes, so keys naming event handlers become live handlers on the breadcrumb button. An attacker who can control the chart configuration can get script to run in the hosting page's origin once a user drills down and interacts with the breadcrumbs. Upgrade to 11.4.9, 12.6.1, or 13.1.0, depending on the release line in use.
