Background
predefine is an npm package that provides functionality for defining and manipulating JavaScript prototypes. It is commonly used in JavaScript applications to extend object prototypes and add new properties or methods. The package is vulnerable to a prototype pollution vulnerability in versions 0.0.0 through 0.1.2.
Vulnerability Detail
The vulnerability in predefine allows an attacker to perform prototype pollution, which can lead to a denial of service (DoS) attack and potentially remote code execution. By manipulating the prototype of an object, an attacker can modify or add properties to all instances of that object, potentially leading to unexpected behavior or security vulnerabilities in the application.
