Book Event Planner

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward event-planner booking helper that uses a disclosed Lokuli MCP endpoint, with privacy caution around contact details needed for bookings.

Install only if you are comfortable using Lokuli to search and book event-planner services. Before creating a booking, confirm the provider, time slot, and any personal contact details that will be sent to Lokuli or the service provider.

A.I.G

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

Medium
Confidence
93% confidence
Finding
The trigger description is broad enough to activate on generic service-booking requests, which can cause the skill to run when the user did not explicitly intend to use Lokuli or transmit booking-related data. In a booking skill that can progress from search to reservation, unintended invocation increases the chance of unnecessary third-party data sharing and user confusion about who is handling the request.

Missing User Warnings

Medium
Confidence
96% confidence
Finding
The skill includes a booking flow that collects and sends personally identifiable information such as name, email, and phone number to an external MCP service, but it does not warn the user or obtain explicit consent before transmission. In this context, that omission is materially risky because the skill is specifically designed to contact a third-party provider and create bookings, so accidental or implicit disclosure of contact details is plausible.
