Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward FlightAware MCP setup guide with disclosed API-key use, optional local output, and user-confirmed alert changes.

Before installing, verify the npm/GitHub package provenance, use an AeroAPI key with the minimum account privileges you need, and keep alert write actions user-confirmed because they can change FlightAware account alert settings and endpoints.

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

Skill accesses MCP server configuration files (mcp.json). MCP configs contain server URLs, authentication tokens, and tool definitions — reading them allows the skill to discover and potentially abuse other tool integrations.
