CVE-2026-44792Network attack vector

SQL injection via crafted Data Table column

Published Jun 23, 2026 · Updated Jun 23, 2026

SQL injection in affected n8n releases allows remote authenticated users with repository write access to alter its PostgreSQL database. During a Source Control Pull, the Data Table importer uses a column name from repository JSON in an internal PostgreSQL query without neutralizing SQL syntax. Exploitation requires PostgreSQL, enabled Source Control, write access to the connected repository, and an administrator-initiated pull.
