Summary
Prototype Pollution in chartkick
Details

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

Upgrade to version 3.2.0 or later.

Severity
7.3 (High)
