Book Tutor

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent tutor-booking connector, but it can send personal contact details to a third-party booking service without clear consent or narrow activation rules.

Review before installing. Use it only when you intend to search or book through Lokuli, and confirm the provider, service, time slot, zip code, name, email, and phone number before allowing any booking call.

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

Finding

The skill includes a booking flow that sends customerName, customerEmail, and customerPhone to a third-party endpoint but provides no warning, consent step, or data-minimization guidance. This is dangerous because users may unknowingly disclose sensitive personal contact data to an external service, creating privacy, compliance, and trust risks if the transfer is unexpected or unnecessary.

Vague Triggers

Confidence

Finding

The trigger description is broad enough to activate on generic tutor-related requests without clearly constraining scope, which can cause the agent to invoke this skill in situations where the user did not intend a third-party booking workflow. In this skill, overbroad triggering is more dangerous because invocation may lead to transmission of location and personal booking data to an external MCP service.
