Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only vehicle-data API skill whose external calls, VIN use, caching, and per-call payment model are disclosed and aligned with its purpose.

Before installing, treat this as a paid external vehicle-data integration: only submit VINs and purchase details you intend to send to Vindex, try the free sample endpoints first, and ensure any x402 wallet/payment setup is under your control before using paid calls.

A.I.G

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
