Poyo Hunyuan 3d 3 1

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward PoYo Hunyuan 3D API helper that discloses its network use and credential requirement, with no evidence of hidden execution, persistence, or unrelated data access.

Install only if you intend to use PoYo for Hunyuan 3D generation. Keep POYO_API_KEY in a server-side environment, review any JSON payload before submission, and avoid sending confidential prompts, private image URLs, or private callback URLs unless you trust PoYo and the receiving endpoint.

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

## Pro Text-to-3D Example

```bash
curl --fail-with-body --request POST \
  --url "https://api.poyo.ai/api/generate/submit" \
  --header "Authorization: Bearer YOUR_API_KEY" \
  --header "Content-Type: application/json" \
Confidence
60% confidence
Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

  --header "Authorization: Bearer ${POYO_API_KEY}" \
  --header "Content-Type: application/json" \
Confidence

Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Medium
Confidence
96% confidence
Finding
The script performs an HTTP POST to an external API and sends the contents of a user-supplied JSON file along with a bearer token from an environment variable. There is no confirmation prompt, logging, or explanatory comment warning the user that local data and credentials will be transmitted off-host.
