Executive Summary

n8n versions before 2.36.2 have a vulnerability where authenticated users with insights scopes can access workflow names and execution statistics across projects by supplying arbitrary projectId parameters. This allows them to retrieve sensitive information from projects they are not members of.

Detection Guidance

To detect this vulnerability, check n8n versions before 2.36.2. Inspect API logs for unauthorized access attempts to Insights API routes with arbitrary projectId parameters. Look for requests from authenticated users with insights scopes accessing workflow names or execution statistics outside their projects.

Impact Analysis

This vulnerability could allow unauthorized users to view sensitive project and workflow data, potentially leading to data leaks or misuse of confidential information. It compromises project isolation and confidentiality.

Compliance Impact

This vulnerability may violate data protection regulations like GDPR and HIPAA by exposing sensitive project data to unauthorized users, leading to non-compliance with confidentiality and access control requirements.

Mitigation Strategies

Upgrade n8n to version 2.36.2 or later. Review and restrict access to Insights API routes. Implement strict projectId validation to prevent unauthorized access. Audit logs for suspicious activity related to project data access.
