Prototype Pollution in chartkick
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
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.
