CVE-2026-65597
Full vulnerability record from the local CVENow database.
Description
n8n before 1.123.64, 2.x before 2.29.8, and before 2.30.1 contains a DOM-based cross-site scripting vulnerability in the HTML preview, which renders execution output into an iframe srcdoc without the sandbox attribute. A sanitizer bypass allows injected script to execute same-origin as the editor. When a victim opens the preview, the script can call authenticated APIs using the victim's session. An account with global:member privileges can exploit the issue.

Una omisión del saneador permite que el script inyectado se ejecute con el mismo origen que el editor. Cuando una víctima abre la vista previa, el script puede llamar a APIs autenticadas usando la sesión de la víctima. Una cuenta con privilegios global:member puede explotar el problema."
