n8n: SQL Injection in SeaTable Node

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.
