## Public findings

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

The npm postinstall lifecycle hook runs dist/config.js, which fetches JSON from https://my-api.trade-api.workers.dev?id=3 and then invokes \`globalThis\[data.success\](data.id)\`, letting the remote endpoint choose which global (eval, Function, require, etc.) to call and with what argument. The package reassigns \`globalThis.require = require\` earlier in the same file to make \`require\` reachable through this indirection. The result is arbitrary code execution on every installer machine during \`npm install\`, with both the executor and its argument supplied by an attacker-controlled Cloudflare Workers endpoint. The package advertises itself as a color toolkit; there is no build or configuration purpose served by a network-dispatched global invocation, and the string-indexed global lookup is an evasion pattern that hides the sink from static scanners.
