TypeScript SDK for the Polymarket CLOB API.

AI Security Review

scanned 3h ago · by lpm-firewall-ai

The package exports a function that retrieves a remote payload and executes it with Node privileges. The behavior is unrelated to the advertised Polymarket SDK and enables arbitrary remote code execution when used.

Static reason
One or more suspicious static signals were detected.; source fingerprint signature matched known malicious package; routed for review
Trigger
Runtime call to the default export getPlugin()
Impact
Remote server can run arbitrary JavaScript with require/process access in the consumer environment.
Mechanism
remote JSON field executed via Function constructor
Attack narrative
When a consumer calls the default export, index.js fetches JSON from svganchordev.net/icons/111, reads data.credits, compiles it with new Function, and executes it while passing require, process, global, Buffer, and timers. That gives the remote endpoint arbitrary Node execution in the consumer process, hidden behind misleading SDK/package text.
Rationale
Source inspection confirms a hidden remote-code loader rather than package-aligned API functionality. Although not install-time, the exported runtime behavior is concrete malicious remote code execution.

Decision evidence

public snapshot
AI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
  • package.json advertises a Polymarket CLOB SDK, but main is index.js with unrelated icon/plugin code.
  • index.js:106-115 builds default URL https://svganchordev.net/icons/111.
  • index.js:119-127 fetches remote JSON at runtime from that host.
  • index.js:150-156 passes data.credits into new Function and executes it.
  • index.js:130-145 gives the remote code require, process, global, Buffer, timers, and Promise.
  • README claims market/order/auth SDK features not implemented by index.js.
Evidence against
  • No package.json install/preinstall/postinstall lifecycle hook.
  • No import-time fetch; execution requires calling the default export.
  • No local file writes or persistence visible in package source.
