Cn Color Converter

Security checks for vulnerabilities and agentic risk

Overview

This is a simple local color-conversion skill with no evidence of hidden access, persistence, credential use, or network behavior.

Install only if a Chinese-language command-line color converter is useful to you. The skill appears local and low-risk, but expect Chinese help/output and note that the documentation includes promotional website links.

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 presents the skill name and nearly all usage documentation in Chinese while the description also includes English text, but it does not state that the skill is Chinese-only or offer any language/locale opt-in. This can violate language/locale policy expectations because users are effectively forced into a specific language experience without an explicit choice or justification.

Finding

The module title and description are presented exclusively in Chinese, and the command-line help and usage text elsewhere in the file follow the same pattern. This effectively forces a specific language for user interaction without offering any language choice or documenting a justified locale restriction.
