GHSA-HWMJ-QG4V-CVG9 n8n: MySQL v1 Node executeQuery Operation Allows SQL Injection via Unparameterized Expression Interpolation

Impact The legacy MySQL v1 node's executeQuery operation substitutes evaluated ... expression values directly into the raw SQL string without parameterization. If a workflow uses this operation with expression-sourced values in the query and is connected to an externally-reachable trigger such as...

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, a...
