Security checks for vulnerabilities and agentic risk

Overview

This skill coherently documents a hosted document-to-video workflow, including its uploads, login requirements, and saved project sessions.

Prompts and attached documents leave your device for dLazy processing, and generation can consume credits. Review the service's privacy and retention terms, choose the intended organization and project, and upload only documents you are authorized to share. Login saves an organization API key locally; revoke it 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

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code only lists organization projects; it does not process documents or perform any video-production step. No context connects project enumeration to the declared workflow, so the demonstrated behavior accesses an unrelated resource and materially differs from the stated purpose.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code only lists organizational projects. It performs no document parsing or video-production steps, and the chunk provides no connection establishing project enumeration as a supporting implementation detail of the declared workflow.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
94% confidence
Finding

The only supplied command performs login rather than the declared conversion workflow. Authentication could support a broader implementation, but the provided chunk neither establishes that connection nor performs any of the described operations. The command alone does not establish credential theft or other malicious behavior.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
93% confidence
Finding

The supplied chunk only invokes a login command; it performs no visible document processing or video production. Authentication could support a larger workflow, but the supplied content establishes no connection between dlazy login and the declared document-to-video purpose. The command's implementation and any credential or network access are not shown.

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.
