CVE-2026-86085Network attack vector

Project-member PII disclosure via missing project scope check

Published Sep 8, 2026 · Updated Sep 8, 2026

Improper authorization in n8n before 2.37.7 and 2.38.0 through 2.38.1 allows remote authenticated users to read project-member PII. The role controller's assignment endpoints check role-type management permission but omit the project:list scope check for the supplied project identifier. Exploitation requires role:manageProject permission and knowledge of an unlisted project identifier, and exposes member names and email addresses only.
