Security audit

Nano Banana Image

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward guide for using AceDataCloud's image generation API and does not show hidden or mismatched behavior.

Before installing, verify the @acedatacloud publisher and only use an AceDataCloud API key you intend to spend with this service. Treat prompts and image URLs as data sent to AceDataCloud, do not paste secrets into prompts, and consider pinning or separately reviewing the optional mcp-nano-banana package if you use it.

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

Privilege Escalation
Confidence
60% confidence
Finding

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