CVE-2026-42237
n8n is an open source workflow automation platform. 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.

n8n versions prior to 1.123.32, 2.17.4, and 2.18.1 are vulnerable to SQL injection through the Snowflake and legacy MySQL v1 nodes. If your workflows use these nodes with user-controlled table or column names, an attacker could execute arbitrary SQL commands against your connected databases. Update to the latest patched versions immediately.
