Security audit

Swap and bridge across 35+ chains with LI.FI

Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed LI.FI helper for cross-chain quotes and transaction data, with expected external API calls and no hidden code or persistence.

Before installing, treat every returned transactionRequest as a real blockchain transaction that can move funds. Verify chain, token, address, amount, slippage, fees, route, contract calls, and ERC20 allowance in the wallet before signing, and expect LI.FI to receive the wallet and transaction details needed to quote or track transfers.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Missing User Warnings

Finding

The README promotes cross-chain swaps, bridges, and DeFi zaps—operations that can trigger irreversible on-chain transactions and token approvals—but does not prominently warn users about loss-of-funds risk, slippage, bridge failure modes, or the need for explicit confirmation before signing. In an agent-execution context, this omission is especially dangerous because users may treat the commands as routine automation and underestimate that the returned transaction requests can move assets permanently across chains.
