A stored Cross-Site Scripting (XSS) vulnerability was identified in the @n8n/n8n-nodes-langchain.chatTrigger node in n8n. If an authorized user configures the node with malicious JavaScript in the initialMessages field and enables public access, the script will be executed in the browser of anyone who visits the resulting public chat URL.
This vulnerability could be exploited for phishing or to steal cookies or other sensitive data from users who access the public chat link, posing a security risk.
This issue has been patched in version 1.107.0 of n8n. Users should upgrade to version 1.107.0 or later.
