How to fix?

Upgrade chartkick to version 3.4.0 or higher.

Overview

chartkick is a Ruby gem that allows creation of JavaScript charts.

Affected versions of this package are vulnerable to CSS Injection. Chartkick is vulnerable to CSS injection if user input is passed to the width or height option.

<%= line_chart data, width: params[:width], height: params[:height] %>

An attacker can set additional CSS properties, like:

<%= line_chart data, width: "100%; background-image: url('http://example.com/image.png')" %>
