Security audit

Book Towing

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed towing-booking integration with no local code, persistence, or hidden behavior, though users should expect contact details to be sent to Lokuli when booking.

Install only if you are comfortable using Lokuli's external MCP service for towing search and booking. Before creating a booking, confirm the provider, time, and contact details, because name, email, and phone are part of the booking request.

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

Missing User Warnings

Confidence
97% confidence
Finding

The skill facilitates sending customer name, email, and phone number to an external MCP endpoint, but it does not warn the user that their personal contact information will be transmitted off-platform. In a booking context, this omission undermines informed consent and can expose users to privacy risks or unexpected third-party data handling.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger description is overly broad because it activates on 'any towing service request' rather than narrowly scoped booking-related intents. This can cause the skill to engage in situations where the user is only seeking general information, increasing the chance of unnecessary external service interaction or premature progression toward booking workflows.
