n8n Node.js Package < 1.123.9 / 2.x < 2.2.1 Stored XSS (CVE-2026-25054)

high Nessus Plugin ID 298989

Language:

Synopsis

The n8n Node.js Package installed on the remote host is affected by a stored cross-site scripting vulnerability.

Description

The version of the n8n Node.js Package installed on the remote host is prior to 1.123.9, or 2.x prior to 2.2.1. It is, therefore, affected by a stored cross-site scripting vulnerability:

 - A cross-site scripting (XSS) vulnerability existed in a markdown rendering component used in n8n's interface, including workflow sticky notes and other areas that support markdown content. An authenticated user with permission to create or modify workflows could abuse this to execute scripts with same-origin privileges when other users interact with a maliciously crafted workflow. This could lead to session hijacking and account takeover.
 (CVE-2026-25054)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to n8n Node.js Package version 1.123.9 or 2.2.1 or later.
