SCA: security update for n8n (GHSA-r6jc-mpqw-m755)

medium Tenable Cloud Security Plugin ID 441004

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 Oracle Database node's select operation allowed user-controlled input passed into the Limit field
 via expressions to be interpolated directly into the SQL query without sanitization or parameterization.
 In workflows where external input is passed into the Limit field (e.g., from a webhook), an attacker could
 inject arbitrary SQL and exfiltrate data from the connected Oracle database. This issue has been patched
 in versions 1.123.32, 2.17.4, and 2.18.1. (CVE-2026-42233)

Solution

Update the n8n library and its related packages to version 1.123.32 or later.
