Details

Prototype pollution vulnerability in 'deep-set' The NPM module 'deep-set' can be abused by Prototype Pollution vulnerability since the function `deepSet()` does not check for the type of object before assigning value to the property. Due to this flaw an attacker could create a non-existent property or able to manipulate the property which leads to Denial of Service or potentially Remote code execution. ### PoC ```js var deepSet = require('deep-set') var obj = {'1':'2'} console.log(obj.isAdmin); deepSet(obj, '__proto__.isAdmin', 'true') console.log(obj.isAdmin); ```
