AAP Agent Bounty

Security checks for vulnerabilities and agentic risk

Overview

This instruction-only skill is clear about verifying proofs and optionally submitting a user-confirmed 0 ETH Base transaction.

Before installing, be comfortable with the skill using your local GitHub auth or optional GH_TOKEN and your user-managed cast signer context. Review the exact transaction command, confirm the target wallet and 0 ETH value, and only set confirm_broadcast: true if you accept public on-chain proof data and any Base gas cost.

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

Finding

The package metadata describes this as an "Instruction-only skill package metadata," which does not match the provided manifest context describing a verification-first helper with optional 0 ETH Base claim submission. This is a semantic mismatch in declared purpose that could mislead reviewers about what the skill is intended to do.
