Security audit

图生视频 即梦首帧 Jimeng I2V

Security checks for vulnerabilities and agentic risk

Overview

The skill describes a coherent cloud video-generation workflow and clearly discloses media uploads, authentication, and local API-key storage.

Upload only media you are comfortable sharing with dLazy and review generation costs. Protect the stored API key, or use DLAZY_API_KEY per invocation to avoid saving it. Check command help because the examples use --image while the options list --firstFrame.

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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
88% confidence
Finding

Authentication could support a video-generation workflow, but the supplied chunk consists solely of a login command. It contains no image or prompt handling, Jimeng invocation, or video-generation operation. The assessment is limited to this chunk; the command's underlying implementation is not provided.

Content

No source excerpt is available for this finding.

Whitespace Padding

Medium
Category
Prompt Injection
Confidence
70% confidence
Finding

Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.
