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.\n\n## Patches\n\nThe 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.\n\n## Workarounds\n\nIf upgrading is not immediately possible, administrators should consider the following temporary mitigations:\n- Restrict n8n instance access to fully trusted users only.\n- Audit and revoke any custom global roles that carry the `role:manageProject` scope, limiting that scope to fully trusted users only.\n\nThese workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.","state":0,"publishedAt":"2026-09-10T21:13:24+00:00","modifiedAt":"2026-09-10T21:30:04.7998691+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"2.38.0"},{"kind":"fixed","version":"2.38.2"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"2.37.7"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-cqr2-h44g-v75v","https://nvd.nist.gov/vuln/detail/CVE-2026-86085","https://github.com/n8n-io/n8n","https://github.com/n8n-io/n8n/releases/tag/n8n@2.37.7","https://github.com/n8n-io/n8n/releases/tag/n8n@2.38.2"],"sourceUrl":"https://github.com/advisories/GHSA-cqr2-h44g-v75v","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-cqr2-h44g-v75v","identifiers":["GHSA-cqr2-h44g-v75v","CVE-2026-86085"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
