CVE-2026-33713Network attack vector

Authenticated SQL injection via orderByColumn expression

Published Mar 25, 2026 · Updated Mar 25, 2026

SQL injection in the n8n Data Table Get node before 1.123.26, 2.13.3, and 2.14.1 allows remote authenticated users to alter database data. The node accepts an expression-derived orderByColumn value and places it into a SQL statement without neutralizing SQL syntax. Workflow creation or editing permission is required; SQLite limits manipulation to one statement, while PostgreSQL permits multiple statements that can modify or delete data.
