This link is maintained to preserve external references.\n\n## Original Description\nn8n contains a sanitizer bypass vulnerability in the legacy expression evaluator's computed-member handler. An authenticated user with workflow create or modify permissions can craft a malicious expression to bypass the sanitizer and achieve host-level code execution as the n8n process. The legacy expression engine is the default in affected versions. Fixed in n8n 1.123.64, 2.29.8, and 2.30.1.","state":2,"publishedAt":"2026-07-22T12:32:17+00:00","modifiedAt":"2026-07-22T22:16:06.7839519+00:00","affected":[{"ecosystem":"npm","name":"n8n","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:L/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":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-pm35-fqvh-cq5g","https://nvd.nist.gov/vuln/detail/CVE-2026-65591","https://www.vulncheck.com/advisories/n8n-before-sanitizer-bypass-remote-code-execution"],"sourceUrl":"https://github.com/advisories/GHSA-m7jc-p4hf-xhwq","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-m7jc-p4hf-xhwq","identifiers":["GHSA-m7jc-p4hf-xhwq"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
