Book Driving Lessons

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward driving-lesson booking connector, but users should expect searches and bookings to involve Lokuli and personal contact details.

Install only if you want Codex to use Lokuli for driving-lesson search and booking. Before any booking is created, confirm the provider, service, time slot, and that your name, email, and phone number will be sent to Lokuli.

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

Finding

The trigger text is broad enough to match generic requests for driving lessons without clearly constraining user intent, increasing the chance the skill is invoked when the user did not explicitly intend to use this third-party booking workflow. Because the skill connects to an external MCP endpoint and can lead to booking actions, unintended invocation could expose user context to a third party or initiate a transactional flow prematurely.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The skill includes a create_booking flow that transmits personal data including name, email, and phone number to an external service, but the description provides no warning or explicit consent step before collection and transmission. In a booking context this increases privacy risk, because users may not realize their personal data will be sent to Lokuli or may provide it without informed consent.
