视频生成 MiniMax H3

Security checks for vulnerabilities and agentic risk

Overview

ClawScan’s verdict is benign: the results describe a video-generation skill with no AIG findings, while noting a mismatch between its stated 2K limit and advertised 4K output; coverage is incomplete because some referenced files or resources were missing.

The verdict is benign, but confidence is medium and the scan is marked partial. Before installing, consider that the documented resolution limit may not match the CLI help, and that the referenced CLI package and other missing resources were not inspected.

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
97% confidence
Finding

The primary purpose and generation modes align with the description, but the explicit 4K resolution option contradicts its stated 2K limit. The other CLI options are supporting implementation details. This chunk is help text rather than an implementation, so actual API behavior and native stereo output cannot be verified.

MCP Tool Poisoning
Confidence
96% confidence
Finding

The generation modes, reference assets, and durations align with the declared purpose. However, the resolution choices explicitly include 4K, contradicting the stated 2K ceiling. Async execution and result downloads are supporting implementation details, not separate mismatches. Only CLI help is supplied, so actual runtime support and native stereo audio cannot be verified.

Category
MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied chunk only executes a login command and does not reference MiniMax Hailuo or implement any declared video features. Authentication could support a broader workflow, but nothing in the supplied code establishes that connection. No credential theft or additional behavior can be inferred from this command alone.

MCP Tool Poisoning
Confidence
96% confidence
Finding

The supplied code performs a login operation rather than the advertised video-generation tasks. Authentication could be a supporting implementation detail if connected to the declared service, but no such connection is established in this chunk.

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.
