Book Notary

Security checks for vulnerabilities and agentic risk

Overview

The skill is coherent for booking notary appointments, but it can send contact details to an external service and create bookings without clear consent or scope guidance.

Review before installing. Use this skill only when you intend to search for or book a notary through Lokuli, and confirm the user understands that their name, email, and phone number may be sent to Lokuli before creating a booking.

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 instructs use of an external MCP endpoint and shows a booking call that transmits personally identifiable information including name, email, and phone number, but it provides no warning or consent language to the user. This is dangerous because users may unknowingly have sensitive contact data sent to a third-party service, creating privacy, compliance, and trust risks, especially for a legal-services-related workflow.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The trigger scope is overly broad because it claims to activate on 'any notary service request' without defining boundaries, eligibility checks, or user-confirmation requirements. In an agent environment, this can cause the skill to be invoked for ambiguous requests and drive users into an external booking workflow they did not explicitly intend, increasing the chance of inappropriate data collection or unintended third-party actions.
