CVE-2026-59253
n8n before 2.28.0 contains an improper authorization vulnerability allowing authenticated users to assign workflows to folders in other projects.
Does this matter?
Lower severity and a low EPSS score (0.28%). Track it; it rarely justifies an emergency change on its own.
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.
