Xueersi Math Word Problem Solver

Security checks for vulnerabilities and agentic risk

Overview

This is a simple math tutoring skill with no code execution, network use, credential access, or persistence.

This skill appears safe to install for math tutoring. Users should expect Chinese-oriented wording and examples, and may need to ask explicitly if they want responses in another language or outside the stated K-9 math context.

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 natural-language description and title explicitly position the skill as a solver for Chinese K-9 math word problems and present the assistant in Chinese, but there is no statement offering language or locale choice. Under the policy for natural-language violations, a skill that implicitly fixes language/locale should provide opt-in or clearly document a justified regional constraint.
