The node assigns output fields via a dot-notation path setter without restricting the field name, allowing an authenticated user to name a field after an inherited built-in method path and corrupt a shared global in the main Node.js process. Because that global is used on the request-authentication path, the instance then fails every authenticated request, causing an instance-wide denial of service for all users until the process is restarted.","state":0,"publishedAt":"2026-08-11T12:17:02.774+00:00","modifiedAt":"2026-08-11T17:50:40.766+00:00","affected":[{"ecosystem":"Vendor product","name":"n8n","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n8n-io\",\n                    \"product\": \"n8n\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/n8n\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"1.123.67\"\n                        },\n                        {\n                            \"version\": \"1.123.67\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"n8n","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n8n-io\",\n                    \"product\": \"n8n\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/n8n\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"2.32.1\"\n                        },\n                        {\n                            \"version\": \"2.32.1\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"n8n","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n8n-io\",\n                    \"product\": \"n8n\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/n8n\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"2.31.5\"\n                        },\n                        {\n                            \"version\": \"2.31.5\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-xwx6-jjhv-84p8","https://www.vulncheck.com/advisories/n8n-before-prototype-pollution-via-edit-fields"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-72749","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-72749","identifiers":["CVE-2026-72749"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
