Highest confirmed finding severity

Medium

1 confirmed security finding requires attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

This report does not block or authorize the manifest or ZIP.

Most static findings are false positives from Markdown examples, GraphQL identifier fields, sample URLs, and HTTP status documentation. One real issue remains: the FastAPI asset presents production guidance while using permissive host, CORS, and bind-address defaults.

Capability review items (1)
Medium
assets/rest-api-template.py:182
Hardcoded IP address
uvicorn.run(app, host="0.0.0.0", port=8000)
The runnable FastAPI template starts Uvicorn on 0.0.0.0, which exposes the service on all interfaces when copied or run. This is a real deployment risk, although it is not malicious exfiltration.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 Medium
assets/rest-api-template.py:1-3assets/rest-api-template.py:21-35assets/rest-api-template.py:180-182
Permissive Production API Template Defaults
The FastAPI asset labels itself production-ready but permits all hosts and CORS origins, then binds to all interfaces when run. Users may copy unsafe defaults into deployed services.
The file directly shows wildcard TrustedHost and CORS settings plus a 0.0.0.0 server binding. TODO comments reduce intent risk, but the production-ready framing makes copy-paste misuse likely.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Medium
    Runnable REST template exposes services on all interfaces by default.
    Default the example server to localhost and document 0.0.0.0 as an explicit deployment choice.
  2. FIX-002
    Medium
    The template uses wildcard TrustedHost and CORS origins while presenting production guidance.
    Replace wildcard values with restricted placeholders and a clear warning to configure allowed hosts and origins.
