Comfyui anfrage

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it claims, but it can send ComfyUI credentials and workflow contents over unencrypted HTTP, so users should review it before installing.

Install only if you trust the configured ComfyUI network path, preferably on localhost or an isolated private network. Avoid setting COMFYUI_USER and COMFYUI_PASS unless the service is protected by a trusted TLS proxy or the skill is updated to support HTTPS and reject plaintext authenticated requests.

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

Undeclared Tool Scope

MCP Least Privilege
Confidence

Finding

The skill uses network access and environment-derived configuration but does not declare an explicit tool scope such as permissions or allowed-tools. That omission weakens security boundaries and reviewability, because consumers cannot easily tell that the skill can make outbound requests and consume secrets from the environment, increasing the chance of unintended access to internal services or credential misuse.

Finding

The CLI submits arbitrary workflow JSON and may include Basic Auth credentials over plain HTTP to a configurable host without any transport security or user disclosure. In this skill context, workflows can contain sensitive prompts, paths, or embedded data, and Basic Auth over HTTP exposes credentials and request contents to interception or modification by anyone on the network path.
