Book Test Prep

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple Lokuli test-prep booking helper, but users should confirm before sending contact details to the external service.

Install only if you intend to use Lokuli for test-prep search or booking. Before creating a booking, confirm the provider, time slot, and any name, email, or phone number that will be sent to Lokuli.

  • 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

Finding

The trigger description is broad enough that the skill may activate on generic test-prep-related requests without clearly establishing that the user wants to search or book through this external service. That can lead to unintended invocation of a booking workflow and premature transmission of user data or provider queries to a third-party MCP endpoint.

Missing User Warnings

Medium
Category

Confidence
96% confidence
Finding

The skill facilitates sending personal contact information such as name, email, and phone number to an external MCP service, but the description does not warn the user that this data will leave the current system. Without clear disclosure and consent, users may unknowingly expose personal information to a third party during booking.
