Security checks for vulnerabilities and agentic risk

Overview

This image-generation skill clearly discloses its cloud uploads, API-key storage, and installation requirements, with no material harmful behavior found.

Use this skill if you are comfortable sending prompts and selected media to dLazy and spending service credits. Keep sensitive files out of generation inputs, protect your API key, and use the pinned installation command.

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
99% confidence
Finding

The code generates images as declared, and super-resolution can reasonably support that purpose. However, video generation and speech narration are materially distinct, undeclared capabilities. The supplied commands also do not implement the advertised automatic selection of an image model based on the prompt.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
98% confidence
Finding

The supplied commands extend beyond the declared image-generation purpose by generating video and speech. Image upscaling can reasonably support image generation and is not independently flagged. The chunk also hardcodes seedream-4.5 rather than demonstrating the advertised automatic model selection.

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.
