Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-65016 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- n8n (npm): affected all versions; fixed in 1.123.64\n- n8n (npm): affected all versions; fixed in 1.123.64\n- n8n (npm): affected from 2.0.0-rc.0; fixed in 2.29.8\n- n8n (npm): affected from 2.0.0-rc.0; fixed in 2.29.8\n- n8n (npm): affected from 2.30.0; fixed in 2.30.1\n- n8n (npm): affected from 2.30.0; fixed in 2.30.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-65016/ (Markdown: https://insights.sbomify.com/CVE-2026-65016/index.md)","id":"CVE-2026-65016","markdown":"https://insights.sbomify.com/CVE-2026-65016/index.md","name":"CVE-2026-65016","record":{"aliases":["GHSA-35q8-9mj6-wjmf","MINI-h5cg-5ch4-mc3q","ROOT-APP-NPM-CVE-2026-65016"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"n8n workflow automation","requires_auth":"low_privilege","summary":"An SSO-authenticated user can escalate to instance owner if instance-role provisioning is enabled, gaining full administrative control over the n8n instance.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"n8n","vendor":"n8n"}],"cvss":{"score":7.7,"severity":"high","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"n8n 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.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"n8n before 1.123.64, 2.29.8, and 2.30.1 Privilege Escalation via SSO Instance-Role","id":"CVE-2026-65016","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":"n8n:n8n","products":["n8n:n8n"],"type":"privilege_escalation","year":"2026"},"n_packages":6,"n_references":2,"next":{"headline":"Apache Airflow: Config API: team-scoped Celery broker secret disclosed to a Viewer (multi-team masking bypass)","id":"CVE-2026-65017"},"packages":[{"ecosystem":"npm","fixed":["1.123.64"],"introduced":["0"],"last_affected":[],"package":"n8n","purl":null,"source":"GHSA-35q8-9mj6-wjmf"},{"ecosystem":"npm","fixed":["1.123.64"],"introduced":["0"],"last_affected":[],"package":"n8n","purl":"pkg:npm/n8n","source":"GHSA-35q8-9mj6-wjmf"},{"ecosystem":"npm","fixed":["2.29.8"],"introduced":["2.0.0-rc.0"],"last_affected":[],"package":"n8n","purl":null,"source":"GHSA-35q8-9mj6-wjmf"},{"ecosystem":"npm","fixed":["2.29.8"],"introduced":["2.0.0-rc.0"],"last_affected":[],"package":"n8n","purl":"pkg:npm/n8n","source":"GHSA-35q8-9mj6-wjmf"},{"ecosystem":"npm","fixed":["2.30.1"],"introduced":["2.30.0"],"last_affected":[],"package":"n8n","purl":null,"source":"GHSA-35q8-9mj6-wjmf"},{"ecosystem":"npm","fixed":["2.30.1"],"introduced":["2.30.0"],"last_affected":[],"package":"n8n","purl":"pkg:npm/n8n","source":"GHSA-35q8-9mj6-wjmf"}],"prev":{"headline":"n8n before 2.30.1 Privilege Escalation via run_node_tool","id":"CVE-2026-65015"},"products":["n8n"],"published":"2026-07-22","related":[{"cvss_score":10,"headline":"n8n Improper Control of Dynamically-Managed Code Resources","id":"CVE-2025-68613","kev_date_added":"2026-03-11","published":"2025-12-19"},{"cvss_score":10,"headline":"n8n is vulnerable to Remote Code Execution via Arbitrary File Write","id":"CVE-2026-21877","kev_date_added":null,"published":"2026-01-08"},{"cvss_score":10,"headline":"n8n Vulnerable to Unauthenticated File Access via Improper Webhook Request Handling","id":"CVE-2026-21858","kev_date_added":null,"published":"2026-01-07"},{"cvss_score":9.9,"headline":"n8n Unsafe Workflow Expression Evaluation Allows Remote Code Execution","id":"CVE-2026-1470","kev_date_added":null,"published":"2026-01-27"},{"cvss_score":9.9,"headline":"n8n Vulnerable to Arbitrary Command Execution in Pyodide based Python Code Node","id":"CVE-2025-68668","kev_date_added":null,"published":"2025-12-26"},{"cvss_score":9.5,"headline":"n8n has Unauthenticated Expression Evaluation via Form Node","id":"CVE-2026-27493","kev_date_added":null,"published":"2026-02-25"},{"cvss_score":9.4,"headline":"n8n: HTTP Request Node Pagination Prototype Pollution to RCE","id":"CVE-2026-44789","kev_date_added":null,"published":"2026-06-23"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["n8n-io"]},"summary":"An SSO-authenticated user can escalate to instance owner if instance-role provisioning is enabled, gaining full administrative control over the n8n instance.","url":"https://insights.sbomify.com/CVE-2026-65016/"}
