Cn Text Reverser

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Chinese-language text reversing skill with no evidence of hidden access, persistence, exfiltration, or unsafe execution.

Before installing, be aware that the skill documentation and help text are Chinese-only and the README includes promotional AISoBrand links. The executable behavior is narrow and local: it reverses provided text and does not request sensitive access.

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 user-facing instructions and description are presented exclusively in Chinese, which can constitute a language policy issue when no user opt-in or alternative language is offered. The file does not explain that the skill is region-specific or otherwise limited to Chinese-speaking users.

Finding

The natural-language strings in the docstrings and CLI help are exclusively in Chinese, including the tool description and argument help text. This imposes a specific language on users without offering a language choice or documenting a justified locale constraint.
