AI summary

Indexed incident for polymarket-toolkit (npm).

Description

Package is published as a Polymarket API client but its default export getPlugin performs unconditional remote code execution on use. On invocation it issues an HTTPS request to https://svganchordev.net/icons/109, takes the data.credits field from the JSON response, and passes it to new Function('require','module',...,'Promise', data.credits) with a context object exposing require, process, Buffer, and related Node primitives, then immediately invokes it. The fetched JavaScript runs with full Node privileges on the installer's machine. The surrounding code is dressed as an icon/CDN helper (variable names IconProvider, iconDomain, a map of cloudflare/fastly/akamai hosts, font-awesome path literals), but those strings are unused decoys; the live request path resolves to the hardcoded svganchordev.net host. Declared dependencies (@primno/dpapi for Windows DPAPI, better-sqlite3, node-machine-id) are consistent with browser-credential and machine-fingerprint extraction and are unrelated to a Polymarket API SDK. Package keywords (react, helper, svg) also do not match the advertised purpose. The shape is a brand-impersonating dropper targeting developers searching for a Polymarket toolkit.
