GHSA-652q-gvq3-74qv: n8n: Snowflake Node executeQuery Operation Allows SQL Injection via Unparameterized Expression Interpolation

July 22, 2026

The n8n Snowflake node’s Execute Query operation interpolated expression values directly into the SQL string, making queries built with untrusted data susceptible to SQL injection.

Exploitation requires that a workflow author has already embedded untrusted expression data directly in a raw SQL query.
