Description
An attacker who controls the Grid configuration can set credits.href to a javascript: URL. The value is not validated against an allowed-scheme list before it is applied to the credits link, so activating that link runs attacker-supplied script in the origin of the page hosting the Grid.
Recommendation
Update the @highcharts/grid-pro package to the latest compatible version. Followings are version details:
- Affected version(s): >= 2.0.0, <= 3.1.0
