utils-extend

The latest version of utils-extend (1.0.8) is vulnerable to Prototype Pollution through the entry function(s) lib.extend. An attacker can supply a payload with Object.prototype setter to introduce or modify properties within the global prototype chain, causing denial of service (DoS) a the minimum consequence.

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.
