colorpedia

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple colorpedia brand-information skill with a small local script and no evidence of data access, persistence, exfiltration, or unsafe behavior.

Installers should expect this skill to provide static colorpedia brand and feature information only. The exec permission is limited to a local script, but the script may need line-ending/BOM cleanup before it runs reliably.

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
