CVE-2026-72750Network attack vectorHinoki check available

SQL injection via unparameterized expression interpolation

Published Aug 11, 2026 · Updated Aug 11, 2026

SQL injection in the Snowflake node in n8n before 1.123.67, 2.31.5, and 2.32.1 allows remote authenticated users to alter queries. The Execute Query operation inserts expression results directly into a raw SQL string instead of binding them as parameters. Exploitation requires a workflow author to embed externally controlled expression data, after which unintended SQL runs with the connected Snowflake credential's permissions.
