Poyo Meshy 6 3d

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed PoYo Meshy 6 API helper that only submits user-prepared 3D generation payloads when explicitly used.

Before installing, understand that using the submit helper will send your prompt, any source image URLs, callback URL, and PoYo API key authorization to PoYo. Keep POYO_API_KEY server-side, avoid private image URLs unless intended, and only run live submissions when you are ready to incur provider-side processing or costs.

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

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
