Security checks for vulnerabilities and agentic risk

Overview

This is a simple Markdown-only skill for summarizing user-provided enterprise WeChat chats, with no code, persistence, credential use, or hidden actions.

Install only if you want an assistant to summarize enterprise WeChat content you provide. Because work chats can contain sensitive business or personal data, review the pasted text or OCR output first and ask the assistant to anonymize names or limit disclosure when needed.

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 trigger description includes broad user phrases such as “提取待办” and “生成周报”, which are common requests that may appear in many contexts outside this specific skill. This can cause unintended invocation on unrelated conversations or documents, increasing the chance that sensitive enterprise chat content is processed or summarized when the user did not intend to use this skill.
