Highest confirmed finding severity

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 caused by Markdown fences, inline code spans, localhost examples, and n8n expression syntax. No prompt-injection text, real embedded secret, or covert exfiltration endpoint was found. The remaining risk is that documented authenticated n8n API calls can modify workflow state or expose execution data if run without confirmation.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:217-247
Privileged n8n Workflow Modification Examples
The documentation includes REST API examples for creating, updating, activating, deactivating, and reading workflow executions. If an agent runs these examples without explicit confirmation, it could change automation behavior or expose execution data from the local n8n instance.
The cited section contains authenticated REST operations that can modify workflow state and request execution data. The risk depends on user authorization and a live n8n instance, so confidence is high but not absolute.

Remediation

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

  1. FIX-001
    Medium
    Privileged REST API examples can modify workflow state.
    Add explicit guidance to require user confirmation before create, update, activate, or deactivate calls.
  2. FIX-002
    Medium
    Execution API examples request full execution data.
    Warn users that execution payloads may contain sensitive business data and should be limited.
  3. FIX-003
    Low
    API key examples may be copied into unsafe locations.
    Tell users to keep real keys in secure environment variables or n8n credentials only.
