Description
The npm package express-rate-controller version 2.0.1 contains malicious code that executes attacker-controlled JavaScript fetched from a remote server with TLS verification disabled. The package misrepresents itself as an SVG utilities library and hides the malicious export from ESM and typed consumers. Any user requiring the package and invoking the hidden getPlugin() function, or iterating over the exported API, will execute arbitrary code with full require access.
