Background
The @dbbhk/ui-components package is an npm library designed for user interface components. It is intended for use in web applications, providing reusable UI elements. However, this package has been found to contain malicious code that executes during the installation process, posing significant security risks to users and their environments.
Vulnerability Detail
The vulnerability originates from the @dbbhk/ui-components@99.0.0 package, which includes preinstall and postinstall hooks in its package.json file that execute a script named callback.js. This script automatically runs when the package is installed via npm, allowing it to query sensitive AWS instance metadata and environment variables for credentials. It indiscriminately collects sensitive information such as AWS IAM role credentials, various API tokens, and other secrets, sending this data to a hardcoded Telegram bot. This poses a severe risk of credential theft and unauthorized access to cloud resources.
How To Fix
This package is malicious. Remove it and rotate any credentials it could have accessed.
npm uninstall @dbbhk/ui-componentsIf it arrived as a transitive dependency, remove the package that pulled it in, then reinstall.
