Security checks for vulnerabilities and agentic risk

Overview

The scanners report a skill made up of one fully inspected Markdown file, with no AIG findings and one low-probability external-transmission flag; the verdict is benign because the request appears aligned with the skill’s stated API purpose.

The verdict is benign with high confidence, and the scan covered the single reported component completely. Before installing, consider that using the skill involves sending a request to ColorBliss’s external API with an API key; the scan does not establish what prompt or photo data may be included in that request.

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
