CVE-2026-54304

n8n is an open source workflow automation platform. Prior to 1.123.55, 2.25.7, and 2.26.1, an authenticated user with permission to create or modify workflows and access to a SecurityScorecard credential with limited allowed domains could configure the SecurityScorecard node's report download operation to target an attacker-controlled URL. The node attached the SecurityScorecard API token to the outbound request, causing the credential to be sent to the attacker-controlled host bypassing credential configured limitations and exfiltrating. This vulnerability is fixed in 1.123.55, 2.25.7, and 2.26.1.

Summary		(es) n8n es una plataforma de automatización de flujos de trabajo de código abierto. Antes de 1.123.55, 2.25.7 y 2.26.1, un usuario autenticado con permiso para crear o modificar flujos de trabajo y acceso a una credencial de SecurityScorecard con dominios permitidos limitados podría configurar la operación de descarga de informes del nodo de SecurityScorecard para apuntar a una URL controlada por un atacante. El nodo adjuntó el token de la API de SecurityScorecard a la solicitud saliente, haciendo que la credencial fuera enviada al host controlado por el atacante, eludiendo las limitaciones configuradas de la credencial y exfiltrándola. Esta vulnerabilidad está corregida en 1.123.55, 2.25.7 y 2.26.1.
