Security audit

视频生成 通义万相 Wan 2.7

Security checks for vulnerabilities and agentic risk

Overview

The skill coherently documents cloud video generation, including its account requirements, local credential storage, and uploads of selected media.

Use media you are comfortable uploading to dLazy and consider generation costs. Login saves an API key locally; environment-variable authentication is also documented. The skill documents were fully reviewed, but the external CLI distribution and service privacy practices were not fully audited.

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

The only supplied command performs login rather than any declared video-generation operation. Authentication could be a supporting implementation detail, but this chunk provides no evidence that dlazy login supports Tongyi Wanxiang. No credential theft or other hidden behavior can be inferred from the command alone.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
88% confidence
Finding

The supplied chunk contains only a login command and implements none of the described video-generation modes. Authentication could support a larger video workflow, but no such workflow or connection to Tongyi Wanxiang is present in the supplied code. There is no evidence of credential exfiltration 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.
