## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The npm package rollup-plugins-check@0.0.2 declares a postinstall script (\`node dist/module.js\`) that, on \`npm install\`, performs an HTTPS GET to https://workconfig.vercel.app with \`rejectUnauthorized: false\` and passes the response body to \`new Function('require', data)(require)\`, executing the fetched code inside the installer's Node.js process with access to \`require\`. The remote body is opaque and controlled by whoever owns the endpoint; TLS certificate verification is explicitly disabled, so any on-path attacker can also substitute the payload. The package advertises itself as a rollup polyfill plugin and ships polyfill code copied from rollup-plugin-polyfill-node as cover, while the dropper is appended to the postinstall entry file. The name resembles the legitimate rollup-plugin-polyfill-node package.
