Image Craft

Security checks for vulnerabilities and agentic risk

Overview

This is a Markdown-only image generation workflow whose tool use is disclosed and proportionate to making stylized 3D images.

Before installing, be aware that the skill may use web search to enrich prompts for public facts about places, brands, and movie scenes, and its broad trigger words may make it activate more often than expected. It does not show evidence of hidden code execution, persistence, credential access, or destructive behavior.

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
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Vague Triggers

Finding

The trigger list includes generic terms such as "portrait," "city," "room," "logo," "brand," "product," "meme," and especially "3D," which commonly appear in ordinary conversation outside this skill's intended scope. Because the description provides only keywords without exclusion conditions or tighter context, the skill could be invoked unintentionally.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The skill manifest and description position this as an image-generation assistant, but the body also instructs use of web_search to fetch external information about cities, brands, and movie scenes. This creates a capability mismatch that can surprise users or policy layers, increasing the risk of unnecessary external data access, prompt-injection exposure from search results, and overbroad permissions relative to the declared purpose.
