Prior to version 1.90.0, n8n is vulnerable to stored cross-site scripting (XSS) through the attachments view endpoint. n8n workflows can store and serve binary files, which are accessible to authenticated users. However, there is no restriction on the MIME type of uploaded files, and the MIME type could be controlled via a GET parameter. This allows the server to respond with any MIME type, potentially enabling malicious content to be interpreted and executed by the browser. An authenticated attacker with member-level permissions could exploit this by uploading a crafted HTML file containing malicious JavaScript. When another user visits the binary data endpoint with the MIME type set to text/html, the script executes in the context of the user\u2019s session. This script could send a request to change the user\u2019s email address in their account settings, effectively enabling account takeover. This issue has been patched in version 1.90.0."}, {"lang": "es", "value": "n8n es una plataforma de automatizaci\u00f3n de flujos de trabajo.
