Security checks for vulnerabilities and agentic risk

Overview

The skill coherently documents image generation through dLazy, including authentication, cloud uploads, and local API-key storage.

Use this skill if you are comfortable sending your prompts and selected images to dLazy and spending service credits. Keep your API key private, review the external CLI before installation, and use the documented dashboard to revoke the key when 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
93% confidence
Finding

The supplied code only invokes a login command; it contains no image-generation or editing operation. Authentication could be a supporting implementation detail, but this chunk provides no evidence connecting dlazy login to Nano Banana Pro or the declared workflows.

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
90% confidence
Finding

The supplied code performs only a login operation rather than the declared image workflow. Authentication could be a supporting implementation detail, but nothing in the supplied material establishes that this command supports Nano Banana Pro. The command alone does not establish credential theft or data exfiltration.

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.
