Background
The safe-object2 package is an npm package that provides a safe way to handle JavaScript objects. It offers various functions and utilities to manipulate and modify objects without the risk of unintended side effects. However, all versions of safe-object2 are vulnerable to Prototype Pollution through the setter function. This vulnerability allows an attacker to modify the prototype of an object, leading to potential security issues and unexpected behavior.
Vulnerability Detail
The vulnerability in safe-object2 arises from a lack of proper input validation and sanitization in the setter function. By crafting malicious input, an attacker can inject arbitrary properties and methods into the prototype of an object. This can result in various security risks, such as remote code execution, privilege escalation, or data manipulation. The severity of this vulnerability is rated as CRITICAL with a CVSS score of 9.8.
