Security audit

视频仿制 Video Replicate

Security checks for vulnerabilities and agentic risk

Overview

The skill’s authentication, media uploads, and video commands are disclosed and fit its stated purpose.

Review the external CLI before installation. Use media you are comfortable uploading to dLazy, check generation costs with --dry-run, and protect the saved API key or use the documented environment-variable option.

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
99% confidence
Finding

Authentication could support a larger implementation, but the supplied chunk shows only a login command and no connection to the declared functionality. As provided, its behavior does not substantiate the stated video-replication purpose. The command alone does not establish credential theft or other malicious activity.

Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

Authentication could support the declared workflow, but the supplied code contains only that setup command and none of the promised video-processing behavior. The assessment is limited to this chunk; it does not establish credential theft or other malicious behavior.

Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

Authentication could support a larger implementation, but the supplied chunk contains only an authentication-setting command. It provides no video input handling, frame or audio extraction, video understanding, or replication-bundle generation. No credential exfiltration or other hidden behavior is evident.

MCP Tool Poisoning
Confidence
94% confidence
Finding

The chunk contains only dlazy login. It shows no video input handling, frame or audio extraction, video understanding, or replication-bundle generation. Authentication could support a larger implementation, but no such implementation or connection to the declared purpose is present in the supplied code.

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.
