This link is maintained to preserve external references.\n\n## Original Description\nn8n versions before 1.123.64, 2.29.8, and 2.30.1 contain a privilege escalation vulnerability in Enterprise SSO instance-role provisioning. The provisioning path maps an IdP-asserted role claim to an n8n global role but does not prevent assignment of the global:owner role (unlike the token-exchange identity path, which rejects it). An SSO-authenticated user whose instance-role claim resolves to global:owner is provisioned as instance owner, gaining full administrative control over workflows, credentials, users, and instance configuration. Exploitation requires that Enterprise SSO is configured, instance-role provisioning is enabled via N8N_SSO_SCOPES_PROVISION_INSTANCE_ROLE (disabled by default), and the attacker controls the instance-role claim value issued by the IdP.","state":2,"publishedAt":"2026-07-22T12:32:17+00:00","modifiedAt":"2026-07-22T22:16:06.8356182+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-35q8-9mj6-wjmf","https://nvd.nist.gov/vuln/detail/CVE-2026-65016","https://www.vulncheck.com/advisories/n8n-before-privilege-escalation-via-sso-instance-role"],"sourceUrl":"https://github.com/advisories/GHSA-mwq7-vcmc-cm4q","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-mwq7-vcmc-cm4q","identifiers":["GHSA-mwq7-vcmc-cm4q"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
