Security audit

图生视频 Vidu Q2

Security checks for vulnerabilities and agentic risk

Overview

The skill coherently documents cloud video generation, including authentication, media uploads, costs, and local credential storage.

Use media you are comfortable uploading to dLazy and check generation costs. Login saves a service key locally. Review the pinned CLI before installing; this inspection covers the skill instructions, not the full external package.

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
Vulnerability Patterns
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

Authentication could support a larger video-generation workflow, but the supplied code shows only a login command, with no connection to Vidu Q2, image inputs, or video generation. As supplied, its behavior does not implement the declared purpose. The chunk does not establish how credentials are handled.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
90% confidence
Finding

The supplied code performs login rather than the declared image-to-video conversion. Authentication could be a supporting prerequisite, but nothing in this chunk connects dlazy login to Vidu Q2 or implements the advertised functionality. The command alone does not establish credential theft or other malicious 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.
