Book Beauty

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward beauty-service booking integration, with disclosed third-party MCP use and no hidden local code or persistence.

Before installing, understand that using this skill can share your beauty-service search details, ZIP code, appointment choices, and booking contact information with Lokuli or a selected provider. Confirm bookings only after reviewing provider, service, time, price, and contact details.

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
92% confidence
Finding
The trigger language is very broad and can cause the skill to activate for loosely related beauty-service requests without clear user intent to use this third-party booking flow. Overbroad activation increases the chance of unintended tool use, unnecessary exposure of user queries and location data to the MCP endpoint, and confusion about whether the assistant is merely giving information or initiating a booking workflow.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill explicitly collects and sends personal contact information such as name, email, and phone number to a third-party booking service, but it does not instruct the agent to provide any privacy notice or obtain informed consent for data sharing. In this context, the workflow makes data transmission likely during normal use, so users may disclose sensitive personal information without understanding who receives it or for what purpose.
