Description

Impact

An authenticated user with permission to create or modify workflows could exploit a SQL injection vulnerability in the Data Table Get node. On default SQLite DB, single statements can be manipulated and the attack surface is practically limited. On PostgreSQL deployments, multi-statement execution is possible, enabling data modification and deletion.

Patches

The issue has been fixed in n8n versions 1.123.26, 2.13.3, and 2.14.1. Users should upgrade to one of these versions or later to remediate the vulnerability.

Workarounds

If upgrading is not immediately possible, administrators should consider the following temporary mitigations:

  • Limit workflow creation and editing permissions to fully trusted users only.
  • Disable the Data Table node by adding n8n-nodes-base.dataTable to the NODES_EXCLUDE environment variable.
  • Review existing workflows for Data Table Get nodes where orderByColumn is set to an expression that incorporates external or user-supplied input.

These workarounds do not fully remediate the risk and should only be used as short-term mitigation measures.
