The editor spliced the field's stored value directly into the node type's URL template without checking for expression syntax. An authenticated member can store a malicious value so that when another user opens the affected node in the editor, the injected expression is evaluated as JavaScript in the victim's authenticated session (cross-user script execution).","published":"2026-08-20T11:21:09.583Z","modified":"2026-08-22T03:58:13.944321233Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77075.json"},{"type":"ADVISORY","url":"https://github.com/n8n-io/n8n/security/advisories/GHSA-fh4c-9rr2-p7qc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77075"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/n8n-before-expression-injection-via-resource-locator"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-22T03:58:13.944321233Z"}}
