Xueersi Idiom Chain Game

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese idiom-chain learning skill with no evidence of hidden access, code execution, or data handling.

Install this if you want an assistant to run a Chinese chengyu chain game and explain idioms. Expect some Chinese-language prompts and examples because that is central to the skill's purpose; no sensitive access or automatic system changes were found.

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 is described and structured as a Chinese chengyu game, and its example triggers, outputs, and required validations assume Chinese-language interaction throughout. There is no indication that users may choose another language for explanations or gameplay, which can violate a language-choice policy when no opt-in is provided.
