Forage Shopping

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed shopping assistant that connects to a remote product-search service, with no local code execution or hidden privileged behavior in the artifact.

Install this only if you are comfortable sending shopping-related queries to the Forage Shopping remote MCP service. Avoid including sensitive personal details in product searches unless you trust that service's data handling.

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

Finding

The trigger guidance is broad enough to activate on many generic shopping-related requests, which can cause the agent to invoke this remote MCP service when the user did not explicitly ask to use it. Because the skill routes queries to an external server and 'no API key required' implies a third-party backend handles requests, unintended invocation can expose user queries to that service and reduce user control over tool use.
