CVE-2020-8147

Flaw in input validation in npm package utils-extend version 1.0.8 and earlier may allow prototype pollution attack that may result in remote code execution or denial of service of applications using utils-extend.

Flaw in input validation in npm package utils-extend version 1.0.8 and earlier may allow prototype pollution attack that may result in remote code execution or denial of service of applications using utils-extend.

All versions of `utils-extend` are vulnerable to prototype pollution. The `extend` function does not restrict the modification of an Object's prototype, which may allow an attacker to add or modify an existing property that will exist on all objects. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available.
