CVE-2026-65593

n8n versions before 1.123.64, 2.29.8, and 2.30.1 contain a server-side request forgery vulnerability in the dynamic-node-parameters endpoints that lack authorization scopes. Authenticated attackers can supply absolute URLs in routing configuration to override baseURL restrictions and make the n8n server issue HTTP requests to arbitrary internal targets when SSRF protection is disabled.

Summary		(es) Las versiones de n8n anteriores a 1.123.64, 2.29.8 y 2.30.1 contienen una vulnerabilidad de falsificación de petición del lado del servidor en los endpoints dynamic-node-parameters que carecen de ámbitos de autorización. Atacantes autenticados pueden proporcionar URLs absolutas en la configuración de enrutamiento para anular las restricciones de baseURL y hacer que el servidor de n8n emita peticiones HTTP a objetivos internos arbitrarios cuando la protección SSRF está deshabilitada.
