Cross-Site Scripting in highcharts

Description

Versions of highcharts prior to 7.2.2 or 8.1.1 are vulnerable to Cross-Site Scripting (XSS). The package fails to sanitize href values and does not restrict URL schemes, allowing attackers to execute arbitrary JavaScript in a victim’s browser if they click the link.

Recommendation

Update the highcharts package to the latest compatible version. Followings are version details:

• Affected version(s): **>= 8.0.0, < 8.1.1

  < 7.2.2**

• Patched version(s): **8.1.1

  7.2.2**
