The CommonJS entry point of cors-security@1.0.1 exposes a getPlugin() API that issues an HTTPS GET to the hardcoded host workconfig.vercel.app and passes the response body directly to new Function('require', data)(require), running attacker-controlled JavaScript inside the consumer's Node process with access to require. TLS certificate verification is disabled on that request (rejectUnauthorized: false). The remote-loader code is present only in the CJS entry and absent from the ESM variant, and does not relate to the package's advertised SVG-utility purpose (name svgcraft, description "Professional zero-dependency SVG utilities"). Any consumer that requires the package and invokes the returned function executes whatever content the operator of workconfig.vercel.app serves at that moment.
