EPSS · scored 2026-10-27

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.

  • WID-SEC-W-2026-3165n8n: Mehrere SchwachstellenDeutsch2026-09-02csaf · cert_bundDE

    Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in n8n ausnutzen, um Sicherheitsmechanismen zu umgehen, beliebigen Code auszuführen oder einen Denial of Service zu verursachen.

  • GHSA-cqr2-h44g-v75vn8n: Cross-Tenant Project-Member PII Disclosure via Missing Per-Project Scope Check on Role Assignment Endpoints2026-09-10ghsa · osvUS

    ## Impact The endpoints `/rest/roles/:slug/assignments` and `/rest/roles/:slug/assignments/:projectId/members` checked only that the caller could manage the role type, not that they could see the project named in the request. A user holding role-management permission could therefore name any project on the instance and read back its members' names and email addresses. The patch adds a project-access check to both routes, hiding projects the caller cannot see and returning not-found for a project it cannot list. ## Patches The issue has been fixed in n8n versions 2.38.2 and 2.37.7. Users should upgrade to one of these versions or later to remediate the vulnerability. ## Workarounds If upgrading is not immediately possible, administrators should consider the following temporary mitigations: - Restrict n8n instance access to fully trusted users only. - Audit and revoke any custom global roles that carry the `role:manageProject` scope, limiting that scope to fully trusted users only. These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
