Security audit

视频生成 PixVerse C1

Security checks for vulnerabilities and agentic risk

Overview

The skill coherently documents cloud video generation, including login, media uploads, and local API-key storage.

Review the external CLI before installation. Upload only media you are comfortable sharing with dLazy, protect the saved API key, and use the documented dry-run option to preview generation costs.

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
94% confidence
Finding

Authentication can be a supporting implementation detail, but the supplied chunk consists entirely of a login command with no demonstrated connection to PixVerse C1 or any declared video-generation mode. Its observable purpose therefore differs materially from the description. The snippet does not establish what credentials or resources the login operation accesses.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
92% confidence
Finding

The supplied chunk contains only a login command and does not invoke PixVerse C1 or implement any declared video-generation mode. Authentication could support a larger video workflow, but no such connection is established in the supplied code. This assessment does not assume any particular credential handling or network behavior.

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.
