视频生成 可灵 Kling V3

Security checks for vulnerabilities and agentic risk

Overview

The skill’s login, saved credentials, and media uploads are clearly disclosed and support its video-generation purpose.

Install if you trust dLazy to process your prompts and selected media and accept generation charges. Login saves an API key locally; use the documented environment-variable option if preferred. Preview requests with --dry-run and revoke the key when no longer needed.

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
Findings (3)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
94% confidence
Finding

The supplied code performs login rather than the declared text-to-video or image-to-video functionality. Authentication could support video generation, but this chunk provides no evidence of that connection or implements the advertised capability.

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
88% confidence
Finding

Authentication can be a supporting implementation detail, but the supplied chunk consists solely of a login command and shows no connection to Kling or a video-generation workflow. Its demonstrated purpose therefore materially differs from the declared purpose. There is no evidence of credential theft or other additional behavior.

Content

No source excerpt is available for this finding.

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.
