Security audit

ashare-market-data-fetcher

Security checks for vulnerabilities and agentic risk

Overview

This skill is a Chinese-language guidance skill for gathering A-share market data, with no hidden persistence, credential access, destructive actions, or automatic execution found.

Installers should treat this as guidance for market-data collection rather than a finished data-fetching implementation. For trading or investment use, verify data sources, permissions, latency, and field definitions independently, especially for Level-2, tick, or commercial 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

声明描述的是一个功能完整的 A股市场数据获取与整理技能，但提供的代码块仅为示例/占位实现，只有打印文本的行为，没有访问市场数据源、处理股票数据、调用外部接口或执行任何相关业务逻辑。因此代码实际行为与声明用途存在实质性不匹配。

Finding

The manifest description and top-level instructions are written as mandatory Chinese-language usage guidance for this skill, and there is no indication that users may request output in another language. This creates a locale/language policy concern because the skill appears to impose a specific language without explicit user opt-in.
