Description
n8n is an open source workflow automation platform. Prior to versions 1.123.9 and 2.2.1, 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. This issue has been patched in versions 1.123.9 and 2.2.1.

Executive Summary

This vulnerability is a Cross-Site Scripting (XSS) issue found in the n8n workflow automation platform prior to versions 1.123.9 and 2.2.1. It exists in a markdown rendering component used in the interface, including workflow sticky notes and other markdown-supported areas.

An authenticated user with permission to create or modify workflows can exploit this vulnerability by crafting malicious markdown content that executes scripts with same-origin privileges when other users interact with the affected workflow.

This can lead to session hijacking and account takeover.

Impact Analysis

The vulnerability can allow an attacker who has workflow creation or modification permissions to execute malicious scripts in the context of other users interacting with the workflow.

This can result in session hijacking, where an attacker can steal session tokens, and account takeover, compromising user accounts.
