CVE-2026-86085

n8n: Cross-Tenant Project-Member PII Disclosure via Missing Per-Project Scope Check on Role Assignment Endpoints

Published Sep 8, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
n8n is an open source workflow automation platform. Prior to 2.37.7 and 2.38.2, the /rest/roles/:slug/assignments and /rest/roles/:slug/assignments/:projectId/members endpoints checked only whether the caller could manage the role type. A caller with role:manageProject could name a project the caller could not list and obtain member names and email addresses. The affected controller is packages/cli/src/controllers/role.controller.ts, which omitted the project:list scope check. This issue is fixed in versions 2.37.7 and 2.38.2.
