NVD description
n8n versions before 2.36.2 contain a missing per-project authorization vulnerability in the Insights API routes that allows authenticated users with insights scopes to access workflow names and execution statistics across projects. Attackers can supply arbitrary projectId parameters to retrieve sensitive project and workflow information from projects they have no membership in.
What to do
- Upgrade n8n to
2.35.4or later (or the patched release of your branch: 2.36.2). - Do not expose the component's API or UI to the internet without authentication in front of it.
