Hupu

Security checks for vulnerabilities and agentic risk

Overview

This is a small Hupu community guide with no code execution, credential access, persistence, or hidden behavior.

Installers should understand that this skill is primarily useful for Chinese-language Hupu content and community interpretation. It does not add automation, account access, or data-changing capabilities.

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 operational guidance and usage instructions are predominantly in Chinese, which can impose a language/locale constraint on users. The policy allows such constraints only when the skill offers a language choice or clearly documents a justified regional limitation, neither of which appears here.
