A member with Editor access to a shared workflow (when workflow sharing is enabled) who knows a target credential's ID can reference that credential in the inline JSON; it passes save-time and runtime validation and resolves in the parent workflow's project context, allowing the attacker to use or exfiltrate credentials they are not permitted to access.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:L","score":7.2},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-639"],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-cj9h-qx8g-pq2g","https://www.vulncheck.com/advisories/n8n-before-credential-exfiltration-via-sub-workflow"],"products":["n8n:n8n"],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-72763","score":0.00358,"percentile":0.2924,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-cj9h-qx8g-pq2g","url":"https://osv.dev/vulnerability/GHSA-cj9h-qx8g-pq2g","summary":"n8n: Shared-Workflow Editor Can Exfiltrate Credentials via Inline Sub-Workflow JSON","modified":"2026-08-12T04:26:17.569111592Z","packages":[{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":["<1.123.67"],"fixed":["1.123.67"]},{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":[">=2.32.0 <2.32.1"],"fixed":["2.32.1"]},{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":[">=2.0.0-rc.0 <2.31.5"],"fixed":["2.31.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
