{"id":"CVE-2026-86085","aliases":["GHSA-cqr2-h44g-v75v"],"url":"https://o3.security/vulnerability/CVE-2026-86085","summary":"n8n: Cross-Tenant Project-Member PII Disclosure via Missing Per-Project Scope Check on Role Assignment Endpoints","details":"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.","published":"2026-09-08T21:20:35.653Z","modified":"2026-09-11T03:30:28.563451330Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"npm","name":"n8n","fixedVersion":"2.38.2"},{"ecosystem":"npm","name":"n8n","fixedVersion":"2.37.7"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/releases/tag/n8n@2.37.7"},{"type":"WEB","url":"https://github.com/n8n-io/n8n/releases/tag/n8n@2.38.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/86xxx/CVE-2026-86085.json"},{"type":"ADVISORY","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-cqr2-h44g-v75v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-86085"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-11T03:30:28.563451330Z"}}
