NewCVE-2026-42229 (opens in a new tab)How to fix?
Upgrade n8n-nodes-base to version 1.121.23, 2.17.2, 2.18.1 or higher.
Overview
n8n-nodes-base is a Base nodes of n8n
Affected versions of this package are vulnerable to SQL Injection via the row:search and row:get operations in the SeaTable node when user-controlled input is passed through expressions into the searchTerm or rowId parameters. An attacker can access unauthorized data from the connected SeaTable base by injecting crafted input that manipulates the underlying SQL query.
Notes: This is only exploitable if the workflow is configured to pass external user input into the affected parameters.
Workaround
This vulnerability can be mitigated by limiting workflow creation and editing permissions to fully trusted users, disabling the SeaTable node by adding n8n-nodes-base.seaTable to the NODES_EXCLUDE environment variable, or avoiding unvalidated external user input in the affected parameters.
