Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

to version 6.0.3 or higher.
kind-of is a package that gets the native type of a value.
Affected versions of this package are vulnerable to Validation Bypass. It leverages the built-in constructor of unsafe user-input to detect type information. However, a crafted payload can overwrite this built in attribute to manipulate the type detection result.
var kindOf = require('kind-of');
var user_input = {
user: 'barney',
age: 36,
active: true,
"constructor":{"name":"Symbol"}
};
console.log(kindOf(user_input));
