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.
