Google Gemini Media

Security checks for vulnerabilities and agentic risk

Overview

This skill is a Gemini media API template guide that openly sends user-selected prompts and media to Google APIs and shows no hidden execution or persistence.

Before installing, confirm you intend to use Google Gemini services and avoid uploading sensitive or unauthorized media. Review costs, quotas, retention, and current Google documentation because the skill includes model names and limits that may change.

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
