NVD Description

Note: Versions mentioned in the description apply only to the upstream n8n package and not the n8n package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

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.
