SCA: security update for @highcharts/dashboards (GHSA-jqgh-w3cc-7jqw)

medium Tenable Cloud Security Plugin ID 477843

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Highcharts JS is a JavaScript charting library based on SVG. From 1.0.0 until 4.2.2, Highcharts Dashboards
 stores DataCursor listener and state maps in plain objects keyed by DataTable ID. A __proto__ table ID
 supplied through dataPool connector configuration resolves to Object.prototype, and sync registration
 creates an enumerable property there whose suffix can be influenced through the sync group option. The
 property is visible on every object, and lasting sync states can throw and stop features such as extremes
 synchronization. Exploitation requires untrusted dashboard configuration and an enabled component sync,
 but no user interaction beyond loading the board. This issue is fixed in 4.2.2. (CVE-2026-118243)

Solution

Update the @highcharts/dashboards library and its related packages to version 4.2.2 or later.
