CVE-2026-65596

n8n before 1.123.64, 2.29.8, and 2.30.1 fails to enforce the "Allowed HTTP Request Domains" restriction on HTTP-based credentials (Header Auth, Basic Auth, Query Auth, OAuth) in the GraphQL node, unlike the HTTP Request node. An authenticated user able to create or edit workflows can point the node's endpoint at a server they control and exfiltrate restricted credentials. Only instances where a credential has "Allowed HTTP Request Domains" configured and is usable by non-owner users are affected.

Summary		(es) n8n antes de 1.123.64, 2.29.8 y 2.30.1 no aplica la restricción ’Allowed HTTP Request Domains’ en credenciales basadas en HTTP (Autenticación por Encabezado, Autenticación Básica, Autenticación por Consulta, OAuth) en el nodo GraphQL, a diferencia del nodo HTTP Request. Un usuario autenticado capaz de crear o editar flujos de trabajo puede apuntar el punto final del nodo a un servidor que controlan y exfiltrar credenciales restringidas. Solo las instancias donde una credencial tiene ’Allowed HTTP Request Domains’ configurado y es utilizable por usuarios no propietarios se ven afectadas.
