Description

n8n is an open source workflow automation platform. Prior to 2.24.0, an endpoint in the Meta and Microsoft Teams trigger nodes reflects a query parameter into the HTTP response without sanitization or Content-Security-Policy headers, enabling reflected XSS in the n8n origin when a logged-in user visits a crafted URL. This vulnerability is fixed in 2.24.0.
