Haresh Cart Management

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small cart-management helper that calls local n8n webhooks and does not include hidden commands or persistence.

Install only if you have the intended local n8n webhooks configured and understand that invoking the skill may change shopping cart state. Review the localhost webhook implementation separately, because this skill only describes calls to it and does not define the server-side behavior.

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
