Security checks for vulnerabilities and agentic risk

Overview

This flight-search skill is a disclosed, purpose-aligned API helper with no local code execution, persistence, or credential use.

Install only if you are comfortable sending flight search details such as cities, dates, passenger counts, and cabin class to the 51smart API. For vague travel conversations, confirm you want a live flight search before allowing an API call.

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

Vague Triggers

Medium
Confidence
94% confidence
Finding
The trigger text is intentionally broad enough to activate on vague travel-related phrases such as wanting to go somewhere and mentioning flying, which can cause the skill to run when the user did not clearly request a flight-price lookup. Over-broad invocation can lead to unintended external API calls and unnecessary disclosure of user itinerary details to a third-party service, increasing privacy and routing risk.
