Book Web Developer

Security checks for vulnerabilities and agentic risk

Overview

This appears to be a simple Lokuli booking helper, but it is overbroadly triggered and can send personal contact details to an external booking service without explicit confirmation instructions.

Review before installing. Use this only when you intentionally want Lokuli to search or book web-developer services, and confirm provider, service, time slot, and contact details before allowing a booking call.

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

High
Confidence
97% confidence
Finding
The skill includes a create_booking flow that transmits customer name, email, and phone number to an external MCP endpoint, but it does not warn that personal contact data will be shared or require explicit user consent immediately before transmission. In a booking context, this makes accidental disclosure of sensitive personal data more likely, especially if the skill is auto-invoked from broad triggers.

Vague Triggers

Medium
Confidence
95% confidence
Finding
The trigger description is broad enough to match generic requests like finding or booking a web developer without clearly constraining geography, provider type, or whether the user actually intends to use Lokuli. That can cause unintended invocation of this skill and premature routing into an external booking workflow, increasing the chance of unnecessary data exposure or unwanted transactions.
