Description
The core-dotenv npm package version 1.4.1 contains malicious code that fetches and executes remote code at runtime. This behavior occurs when calling its config() or get() functions, which trigger an obfuscated HTTPS request to a remote server. The response is executed with full Node.js privileges, allowing arbitrary code execution on the host. This package should be considered fully compromised, and any system using it is at high risk.
