Security audit

Book Spa

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent spa-booking integration, but it can create external bookings with personal contact details without clearly requiring user confirmation or limiting when it activates.

Review this skill before installing. It appears to do what it claims, but users should only use it when they intend to search or book spa appointments, and should confirm provider, service, time slot, and the exact contact details before allowing any booking call.

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

Missing User Warnings

Finding

The skill includes a booking operation that transmits personal contact details such as name, email, and phone number to an external service, but the skill description provides no user-facing warning, consent step, or disclosure about this data transfer. This is dangerous because users may unknowingly expose sensitive personal data to a third party, creating privacy, compliance, and trust risks.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger description is broad enough to activate on generic spa-related requests without clearly constraining scope or confirming user intent. This can cause unintended invocation of an external booking workflow, increasing the chance of sending user queries or progressing toward actions the user did not explicitly ask to perform.
