SQLi PostgreSQL

Description

n8n is an open source workflow automation platform. Prior to versions 2.14.1, 2.13.3, and 1.123.26, 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. 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. 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, and/or 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.

Analysis

SQL injection in n8n's Data Table Get node allows authenticated users with workflow modification permissions to execute arbitrary SQL queries against PostgreSQL backends, enabling data modification and deletion. Public exploit code exists for this vulnerability. …

Remediation

Within 24 hours: Identify all n8n instances in your environment and determine which use PostgreSQL versus SQLite backends; restrict workflow creation/modification permissions to essential personnel only. Within 7 days: Implement network segmentation to limit n8n database access, disable the Data Table Get node if unused, and apply input validation/WAF rules to detect SQL injection patterns in workflow definitions. …
