A sanitizer bypass allows injected script to execute same-origin as the editor. When a victim opens the preview, the script can call authenticated APIs using the victim's session. An account with global:member privileges can exploit the issue.","state":0,"publishedAt":"2026-07-22T12:18:19.913+00:00","modifiedAt":"2026-10-29T20:17:32.97+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:L/VA:N/SC:H/SI:L/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:L/UI:R/S:C/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-p3rg-hrf9-w9gj","https://www.vulncheck.com/advisories/n8n-before-dom-based-xss-via-unsandboxed-iframe"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-65597","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-79"],"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:2.30.0:*:*:*:community:node.js:*:*","cpe:2.3:a:n8n:n8n:2.30.0:*:*:*:enterprise:node.js:*:*"],"sourceDates":{"published":"2026-07-22T12:18:19.913","lastModified":"2026-10-29T20:17:32.970"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
