Book Car Wash

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward car-wash search and booking helper that uses a disclosed Lokuli MCP endpoint, with privacy and confirmation cautions but no evidence of hidden or malicious behavior.

Before installing, understand that booking through this skill uses Lokuli's external MCP service and may require sharing your name, email, and phone number. Confirm provider, service, time, and contact details before allowing any booking request to be sent.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Finding

The activation text is broad enough to trigger on generic car-wash requests without clearly constraining when the skill should be invoked or whether user confirmation is needed before using an external booking service. That increases the chance of over-invocation and unintended routing of user requests into a workflow that may search or book through a third-party MCP endpoint.

Missing User Warnings

Medium

Confidence
96% confidence
Finding

The skill documents collection and transmission of customerName, customerEmail, and customerPhone to an external MCP service but does not warn the user that their personal contact data will be sent off-platform. This creates a meaningful privacy and consent risk because users may not realize that external processing is involved before sensitive personal information is shared.
