Security checks for vulnerabilities and agentic risk

Overview

The skill coherently supports Haola checkup bookings, with expected access to sensitive personal information and a minor disclosure gap.

Booking may send identity and health information to Haola. Prefer provider forms over chat for sensitive fields, review OAuth permissions, and clearly specify any profile updates or appointment changes. The remote service's implementation and retention practices were not verified.

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

Findings (1)

The remote MCP workflow lacks a user warning that sensitive booking information will be sent to the external service.

Finding

These instructions direct the agent to invoke the remote Haola service, including through generated scripts that POST tool-call parameters. The booking workflow permits collecting identity information in the conversation, but its warning at L53 only covers conversation visibility and client logging—not transmission to the external provider.
