Cn Color Scheme Generator

Security checks for vulnerabilities and agentic risk

Overview

This is a simple local color-palette generator with no hidden system access, though its documentation includes an unrelated promotional link in Chinese.

Reasonable to install for local palette generation. Be aware that the README contains a promotional external website link that is not needed for the skill to work.

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 main skill documentation is in English, but the closing promotional section switches to Chinese-only text. This creates a language/locale policy concern because users are not given an opt-in choice and the locale constraint is not explained as region-specific or necessary for the skill's function.
