CVE-2026-42229

n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, a flaw in the SeaTable node's row:search and row:get operations allowed user-controlled input to be concatenated directly into SQL query strings without escaping or parameterization. In workflows where external user input is passed via expressions into the SeaTable node's search or row retrieval parameters, an attacker could manipulate the constructed query to retrieve unintended rows from the connected SeaTable base, bypassing row-level filtering logic implemented in the workflow. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1.

Analysis

n8n versions prior to 1.123.32, 2.17.4, and 2.18.1 contain a SQL injection vulnerability in the SeaTable node. If your automation workflows pass user-supplied input directly into SeaTable search or row retrieval operations, an attacker can manipulate the query to access unauthorized data. Users should update their n8n instances to the latest patched versions immediately.
