Medium

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

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Third-party content exposure detected (high risk: 0.70). The skill explicitly forks and queries mainnet using third‑party RPC endpoints (e.g., vm.createSelectFork("https://eth-mainnet.alchemyapi.io/v2/...") and network.provider.request with jsonRpcUrl/process.env.MAINNET_RPC_URL) and interacts with public on-chain contracts (e.g., Uniswap, DAI), which are untrusted, user-generated third‑party data that the agent reads and uses to drive test logic and actions.

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

What this means

The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.

Why it was flagged

Direct money access detected (high risk: 1.00). The skill is explicitly tailored to blockchain/DeFi development and includes concrete crypto execution capabilities: it shows using a PRIVATE_KEY in network accounts, invoking token.transfer and ERC20 interactions, performing Uniswap swaps (mainnet fork), impersonating accounts to move tokens, and using RPC/mainnet forking. These are explicit crypto/blockchain actions (wallet signing, swaps, token transfers) rather than generic tooling, so it grants direct financial execution capability.
