The node-internal-svg-loader npm package versions 1.0.0 and 1.0.1 contain malicious code that fetches JavaScript from an untrusted external domain and executes it via eval in the Node.js environment. This allows arbitrary code execution with full access to the host system. Any system with this package installed should be considered fully compromised, and all secrets on the system should be rotated immediately. Removal of the package alone may not eliminate the compromise.
