MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (medium risk: 0.30). The Neynar webhook listener runtime path (POST /api/webhook using express.raw) parses and logs event.data after verifying X-Neynar-Signature, but the webhook payload originates from Neynar-delivered events that are ultimately driven by outsider-authored Farcaster content (e.g., casts/text), making the ingested free text attacker-controlled.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The server serves an HTML page that performs a runtime ES module import from https://esm.sh/@farcaster/frame-sdk which fetches and executes remote JavaScript in clients (remote code executed at runtime and relied on by the Mini App), so this is a runtime external dependency that executes remote code.

MEDIUM W009: Direct money access capability detected (payment gateways, crypto, banking).

• Direct money access detected (high risk: 1.00). The skill explicitly documents and provides code for sending onchain transactions via an embedded wallet provider (EIP-1193) and examples using viem and wagmi to call sendTransaction (specifying to, value, calldata). These are concrete crypto/blockchain wallet transaction APIs — i.e., direct financial execution capability.
