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.","published":"2026-08-11T13:19:05.960","modified":"2026-08-11T13:19:05.960","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-xwx6-jjhv-84p8"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/n8n-before-prototype-pollution-via-edit-fields"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-11T13:19:05.960"}}
