Technical description
n8n before 1.123.69, 2.x before 2.33.4, and 2.34.x before 2.34.1 contain an arbitrary file read and write vulnerability in the Snowflake node, which passes free-form Execute Query input, including client-side commands, directly to the Snowflake SDK without applying n8n's file-access restrictions. An authenticated user with usable Snowflake credentials can upload a local file from the n8n host or overwrite an existing file with a staged one.
