Security audit

three

Security checks for vulnerabilities and agentic risk

Overview

This is a simple informational bilingual skill about the cultural meaning of the number 3, with no code execution or sensitive access.

Installers should expect this skill to answer number-3 symbolism questions using Chinese and English material. If a single language is preferred, users may need to ask for that explicitly, but there is no evidence of hidden behavior, unsafe access, or persistence.

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 manifest description states the skill is '中英文双语' and the document is structured as fixed Chinese and English versions. This can violate language/locale policy expectations because it imposes a specific output language format rather than offering the user's preferred language as a choice.
