Prototype Pollution in chartkick

Description

Affected versions of @polymer/polymer are vulnerable to prototype pollution. The package fails to prevent modification of object prototypes through chart options containing a payload such as {"__proto__": {"polluted": true}}. It is possible to achieve the same results if a chart loads data from a malicious server.

Recommendation

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

• Affected version(s): >= 3.1.0, <= 3.1.3
• Patched version(s): 3.2.0
