Airport Pickups London

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Airport Pickups London booking integration that sends expected trip and passenger details to its API with an explicit booking-confirmation rule.

Before installing, understand that your agent will connect to Airport Pickups London's remote MCP/API service and may send passenger contact details, trip locations, and flight numbers. Confirm any booking, amendment, or cancellation before allowing the agent to proceed.

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

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
