Security checks for vulnerabilities and agentic risk

Overview

This is a simple ecommerce recommendation-writing skill with no executable code or hidden system access.

Before installing, confirm that Chinese-language operating guidance is acceptable for your team. Treat any product, pricing, margin, inventory, or promotion information you provide as business-sensitive, but the skill itself does not request privileged access or perform actions outside drafting recommendations.

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

Natural-Language Policy Violations

Medium
Confidence
95% confidence
Finding
The skill description switches into Chinese for its core user-facing guidance and does not indicate that other languages are supported or that language is selectable. This creates a locale/language policy concern because the skill implicitly constrains interaction language without explicit opt-in or justification.
