Jimeng AI Image Generation
Security checks for vulnerabilities and agentic risk
Overview
This skill is a disclosed Jimeng/Volcengine image-generation helper that uses user-provided prompts and configured API keys for its stated purpose.
Install only if you intend to use Volcengine Jimeng and are comfortable sending prompts and optional reference image URLs to that service. Keep the Secret Key private, store it only in environment variables or a secret manager, and use --force-single when you want to limit image-generation cost.
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

This markdown file includes instructions for obtaining and setting an Access Key and Secret Key in environment variables. Because it handles credentials, the skill description should include a brief warning not to share, log, or commit the Secret Key to reduce accidental exposure risk.
