n8n: Snowflake Node executeQuery Operation Allows SQL Injection via Unparameterized Expression Interpolation
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.
The issue has been fixed in n8n versions 1.123.67, 2.31.5, and 2.32.1. Users should upgrade to one of these versions or later to remediate the vulnerability. The fix introduces an optional "Query Parameters" field that allows values to be bound via positional placeholders rather than interpolated into the query string.
If upgrading is not immediately possible, administrators should consider the following temporary mitigations:
executeQuery operation and ensure no expression resolving to externally-controlled data is embedded directly in a raw SQL query string.executeQuery nodes.These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
