CVE-2026-72771

n8n versions before 2.32.1 fail to enforce the Allowed HTTP Request Domains allowlist in multiple AI and LLM nodes when user-supplied base or endpoint URLs are configured. Low-privileged workflow editors with use-only access to shared credentials can redirect requests to attacker-controlled hosts and exfiltrate credential secrets for reuse against underlying services.

Summary		(es) Las versiones de n8n anteriores a la 2.32.1 no logran hacer cumplir la lista de permitidos de Dominios de Solicitudes HTTP en múltiples nodos de IA y LLM cuando se configuran URLs base o de punto final proporcionadas por el usuario. Editores de flujo de trabajo con bajos privilegios y acceso de solo uso a credenciales compartidas pueden redirigir solicitudes a hosts controlados por el atacante y exfiltrar secretos de credenciales para su reutilización contra servicios subyacentes.
