CPA Calculator Ecommerce

Security checks for vulnerabilities and agentic risk

Overview

This is a simple ecommerce CPA calculation guide with no executable behavior, persistence, or access to user systems.

Before installing, note that the skill appears intended for Chinese-language use unless the user asks otherwise. It is otherwise low risk: it is a calculation template that relies on user-provided business assumptions and does not run code or access external data.

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 file's user-facing instructions and descriptions are presented in Chinese, but there is no indication that the skill is region-specific or that users may opt into another language. This can violate language/locale policy when users are not given a choice or informed of the constraint.
