CVE-2026-33713

Ein entfernter, authentisierter Angreifer kann eine Schwachstelle in n8n ausnutzen, um einen SQL-Injection Angriff durchzuführen.

## 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.
