Security checks for vulnerabilities and agentic risk

Overview

This skill is a small, disclosed FactorHub integration for China A-share market data and does not show hidden execution, persistence, or data-exfiltration 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

Finding
The skill manifest description and README content are entirely in Chinese, which effectively imposes a language/locale constraint on users. There is no indication that the skill supports language choice, user opt-in, or that the restriction is explicitly justified as a region-specific requirement.
