Security audit

Feng Shui API

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent Feng Shui API connector, with a disclosed but risky CLI install fallback users should verify before running.

Before installing, confirm you trust OOMOL and the oo CLI installer source, especially because the setup examples execute remote installer scripts. For normal use, expect the skill to run Feng Shui API read actions through your connected OOMOL account.

  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Script Fetching

High
Category
Supply Chain
Confidence
97% confidence
Finding

The skill instructs users to install software by piping a remotely fetched script directly into a shell, which is a classic supply-chain execution risk. If the hosting domain, TLS session, or install script is compromised, arbitrary code would run immediately on the user's machine with the user's privileges.
