n8n before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 contains a stored cross-site scripting vulnerability because some webhook response paths, such as error responses and responses without headers, omit the sandbox Content-Security-Policy. Authenticated members who can create and activate workflows can serve HTML that runs on the n8n origin, letting scripts act with the session of users who open the webhook URL.
