Aviation Agent

Security checks for vulnerabilities and agentic risk

Overview

The skill’s weather-fetching behavior is narrow and coherent, but it gives aviation go/no-go and regulatory guidance without clear safety limitations or official-source verification requirements.

Review this carefully before installing. The script itself appears limited to fetching public aviation weather, but the skill should not be used as the sole basis for real flight decisions or regulatory compliance; users should verify against official FAA/NWS/Flight Service sources and qualified aviation judgment.

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

High
Category
MCP Tool Poisoning
Confidence
94% confidence
Finding
The skill claims to provide FAA quick reference, VFR/IFR minimums, and go/no-go decision support, but the described implementation only fetches weather and shows basic flight categories. In a safety-critical aviation context, this mismatch can cause users to rely on missing or incomplete regulatory and operational guidance when making flight decisions.

Missing User Warnings

High
Confidence
94% confidence
Finding
The skill advertises go/no-go decision support for pilots without an explicit warning that it is not a substitute for an official weather briefing, current FAA materials, instructor judgment, or PIC responsibility. In aviation, omission of such warnings can encourage unsafe reliance on incomplete automation for real-world flight safety decisions.

Lp3

Medium
Category
MCP Least Privilege
Confidence
84% confidence
Finding
The skill describes functionality that requires network access to aviationweather.gov, but it does not declare any explicit tool scope or permissions boundary. In practice this can lead to overbroad runtime access, weaker reviewability, and accidental use of network capabilities outside what users or the platform expect.

Vague Triggers

Medium
Confidence
91% confidence
Finding
The trigger text includes broad phrases like general aviation weather and regulatory questions, which could cause the skill to activate in situations outside its narrow, validated use cases. Unintended invocation matters here because the skill operates in a safety-sensitive domain and may present itself as more authoritative or comprehensive than it is.
