Security checks for vulnerabilities and agentic risk

Overview

The skill’s disclosed authentication, media uploads, and video-generation workflow fit its stated purpose.

Install only if you accept dLazy receiving your supplied prompts and media and charging generation credits. Protect the saved API key. Consult command help because the examples use inconsistent image flags and output types.

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
92% confidence
Finding

Authentication could support a video-generation workflow, but the supplied chunk contains only a login command and establishes no connection to Jimeng or video generation. Its demonstrated primary behavior therefore differs from the declared purpose. The command alone does not establish credential theft or other malicious activity.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
88% confidence
Finding

The supplied code contains no image handling, Jimeng model invocation, or video generation. Authentication can be a supporting implementation detail, but this chunk provides no evidence that the dlazy login operation supports the declared workflow. Its only observable operation is login rather than video generation.

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.
