Description
n8n before 1.123.67, 2.31.5, and 2.32.1 contains a SQL injection vulnerability in the Snowflake node's Execute Query operation, which interpolates expression values directly into the SQL string. When a workflow author embeds untrusted, externally-controlled expression data directly in a raw SQL query, that data is not parameterized, allowing SQL injection. The fix adds an optional 'Query Parameters' field to bind values via positional placeholders.
