Security checks for vulnerabilities and agentic risk

Overview

The skill coherently supports hosted video generation and clearly discloses its login, file uploads, and saved project sessions.

Use documents you are comfortable sending to dLazy, check generation costs, and remember that login saves an organization API key locally. Prefer device-code login and revoke the key when access is 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 (5)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code only lists organization projects; it performs none of the declared video-generation workflow. No context establishes project enumeration as a supporting implementation detail, so the observed behavior accesses organizational resources outside the stated purpose.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
97% confidence
Finding

The supplied code only lists organizational projects; it contains no video-generation behavior or demonstrated connection to that workflow. As provided, its primary behavior is project discovery rather than the declared explainer-video functionality.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
94% confidence
Finding

The supplied code performs only a login operation rather than the described explainer-video workflow. Authentication could support a video service, but the supplied material does not establish that relationship. The command alone does not demonstrate credential theft or other malicious behavior.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
90% confidence
Finding

The supplied code performs only a login operation, which materially differs from the declared purpose. Authentication could support a video service, but the chunk provides no evidence connecting this command to such a workflow. The command alone does not establish credential theft or other malicious behavior.

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.
