A crafted non-string value supplied from a workflow expression into the text or HTML body field can be interpreted by the underlying mail library (Nodemailer) as a file path or URL, allowing arbitrary local file disclosure and server-side request forgery (SSRF). Exploitation requires a pre-existing active workflow with an unauthenticated webhook, valid SMTP credentials configured on the node, and untrusted input mapped directly into the body field; this is not a default configuration.","state":0,"publishedAt":"2026-08-11T13:19:06.807+00:00","modifiedAt":"2026-10-24T15:10:00.19+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:L/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.2,"severity":"HIGH"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-2x35-3fw4-9jr4","https://www.vulncheck.com/advisories/n8n-before-arbitrary-file-read-via-send-email-node"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72766","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-843"],"productCriteria":["cpe:2.3:a:n8n:n8n:*:*:*:*:community:node.js:*:*","cpe:2.3:a:n8n:n8n:*:*:*:*:enterprise:node.js:*:*","cpe:2.3:a:n8n:n8n:2.32.0:*:*:*:community:node.js:*:*","cpe:2.3:a:n8n:n8n:2.32.0:*:*:*:enterprise:node.js:*:*"],"sourceDates":{"published":"2026-08-11T13:19:06.807","lastModified":"2026-10-24T15:10:00.190"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
