Background
The com.apple.unityplugin.storekit package is an npm module that is designed to interface with Apple's StoreKit framework for Unity applications. It is intended to facilitate in-app purchases and other store-related functionalities. However, this package has been found to impersonate an internal namespace of Apple, leading to significant security concerns due to embedded malicious code.
Vulnerability Detail
The vulnerability originates from the package com.apple.unityplugin.storekit, which performs an unauthorized HTTPS GET request to a hardcoded subdomain upon being required. This request transmits sensitive information such as the package name, operating system platform, and hostname of the machine. This behavior is executed unconditionally at module load, without any documentation or opt-in from the user, making it a severe security risk. The malicious code can lead to data leakage and potential exploitation by confirming that an internal build system has resolved the attacker's public package instead of the legitimate one.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall com.apple.unityplugin.storekitIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
