Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Amazon-data API helper with bounded network behavior, user-controlled paid access, and no evidence of hidden persistence or unrelated data collection.

Install only if you are comfortable sending Amazon product, seller, keyword, and optional feedback details to Apiguru. Do not provide an API key or use paid calls unless you approve the cost and scope, and treat the optional MCP package/server instructions as separate software that should be reviewed before use.

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
