AI Powered Q&A
Can you explain this vulnerability to me?
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.
How can this vulnerability impact me? :
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.
