Ai Imggen2

Security checks for vulnerabilities and agentic risk

Overview

The skill appears intended for image generation, but it under-discloses where prompts and API keys are sent and exposes the API key through command-line arguments.

Review this skill carefully before installing. Use only non-sensitive prompts, prefer a limited or disposable API key, and be aware that the key and prompt are sent to api.heybossai.com even though the setup note references skillboss.co. The documented command can expose the API key through shell history, process listings, logs, or monitoring tools; rotate the key if it may have been captured.

Vulnerability Patterns
  • Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
  • 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

Category
MCP Least Privilege
Confidence
94% confidence
Finding

This script performs outbound network access to a third-party API but the capability is not covered by declared permissions. In an agent/skill environment, undeclared network behavior is dangerous because it can exfiltrate user-supplied data and secrets without the platform or user having transparent permission visibility.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

The skill instructs the user to pass an API key on the command line and to download a returned URL, but it does not warn about credential exposure or external network transfer. Command-line secrets can leak via shell history or process inspection, and blindly fetching a URL from script output can cause unintended data transfer to untrusted destinations.

External Transmission

Medium
Category
Data Exfiltration
Confidence
87% confidence
Finding

The script sends user input and a provided API key to an external service at api.heybossai.com. This is expected for an image-generation integration, but it is still a real security/privacy concern because sensitive prompts or credentials are transmitted off-platform to a third party.
