n8n Workflow: Remediate Neo4j Attack Paths with OpenAI, Jira & GitHub

Remediate Neo4j attack paths faster—using OpenAI, Jira, and GitHub

This n8n workflow scans your Neo4j-compatible security graph, automatically identifies the riskiest attack paths between internet-facing assets and crown-jewel resources, and then drives remediation to completion by creating a Jira ticket and opening a GitHub pull request with an updated Infrastructure-as-Code (IaC) fix—powered by OpenAI.

What this workflow does

• Runs on a schedule or manually: daily automation via a scheduled trigger, or you can run it on demand.
• Finds shortest-path attack routes in Neo4j: queries your Neo4j-compatible security graph to identify shortest paths from internet-facing assets to critical (crown-jewel) resources.
• Parses, scores, and selects high-risk paths: structures candidate paths and applies risk scoring criteria, then picks the highest-risk path above a configured threshold.
• Fetches the relevant IaC from GitHub: retrieves the Infrastructure-as-Code file associated with the finding.
• Uses OpenAI to generate remediation details and a corrected file: produces a detailed remediation summary, step-by-step guidance, ticket/PR metadata, and the corrected IaC content.
• Creates a Jira issue: opens a Jira Software Cloud ticket describing the finding and the proposed fix.
• Opens a GitHub PR with the fix: creates a new branch, commits the corrected IaC file, and opens a pull request referencing the Jira ticket.
• Closes the loop: posts the pull request link back to the Jira issue.

Use cases

• Continuous security graph monitoring for SaaS operations teams.
• Accelerated remediation workflows when Neo4j highlights risky exposure routes.
• IaC patch management with traceability between Jira findings and GitHub PRs.

Technical details

• Integrations: Neo4j-compatible security graph, GitHub, Jira Software Cloud, OpenAI.
• Key nodes used: if, set, code, wait, sticky note, http request.
• Setup highlights: add Neo4j HTTP Basic Auth to the security graph query node; add GitHub credentials (repo scope) to GitHub request nodes; add Jira (email + API token) to Jira request nodes; add OpenAI API key to the OpenAI Chat Model node; update Neo4j URL and the risk score threshold in “Set - Config”.
