Description
Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-2xgm-wc4g-5jvg. This link is maintained to preserve external references.
Original Description
n8n before 2.28.0 contains an improper authorization vulnerability allowing authenticated users to assign workflows to folders in other projects. Attackers can bypass project and folder authorization boundaries by supplying crafted request payloads during workflow creation, causing logical integrity violations in target project folder structures.

Weakness
CWE-639: Authorization Bypass Through User-Controlled Key
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
How to prevent it
- Architecture and Design: For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
- Architecture and Design, Implementation: Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
- Architecture and Design: Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
