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

Findings (4)

Lp3

Medium

Category: MCP Least Privilege
Confidence: 70% confidence
Finding: Without declared permissions the skill's intent is opaque and cannot be validated.

Natural-Language Policy Violations

Medium

Confidence: 96% confidence
Finding: This code file contains natural-language instructions, examples, help text, and runtime messages only in Chinese. Under the policy rule for language/locale constraints, forcing a specific language without offering a user choice or documenting a justified region-specific limitation is a violation.

Natural-Language Policy Violations

Low

Confidence: 90% confidence
Finding: The file forces a single language presentation for all instructions and API usage details. Under the language/locale policy, this can be a violation unless the skill offers user choice or clearly documents that the content is intended only for a specific locale or audience.

Missing User Warnings

Low

Confidence: 81% confidence
Finding: 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.
