Prior to versions 1.123.32, 2.17.4, and 2.18.1, the fix for GHSA-f3f2-mcxc-pwjx did not cover the Snowflake node or the legacy MySQL v1 node. Both nodes construct SQL queries by directly interpolating user-controlled table names, column names, and update keys into query strings without identifier escaping, enabling SQL injection against the connected database. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N","score":5.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-89"],"references":["https://github.com/n8n-io/n8n/security/advisories/GHSA-hp3c-vfpm-q4f7"],"products":["n8n:n8n"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-42237","score":0.00254,"percentile":0.16967,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hp3c-vfpm-q4f7","url":"https://osv.dev/vulnerability/GHSA-hp3c-vfpm-q4f7","summary":"n8n has SQL Injection in Snowflake and MySQL Nodes","modified":"2026-05-08T01:50:30.567248Z","packages":[{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":["<1.123.32"],"fixed":["1.123.32"]},{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":[">=2.18.0 <2.18.1"],"fixed":["2.18.1"]},{"ecosystem":"npm","name":"n8n","purl":"pkg:npm/n8n","ranges":[">=2.0.0 <2.17.4"],"fixed":["2.17.4"]}]}],"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).
