CVE-2026-44789

n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could achieve global prototype pollution via an unvalidated pagination parameter in the HTTP Request node. Combined with other techniques this could lead to RCE on the instance. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7.

Summary		(es) n8n es una plataforma de automatización de flujos de trabajo de código abierto. Antes de 1.123.43, 2.22.1 y 2.20.7, un usuario autenticado con permiso para crear o modificar flujos de trabajo podría lograr la contaminación global de prototipos a través de un parámetro de paginación no validado en el nodo HTTP Request. Combinado con otras técnicas, esto podría llevar a RCE en la instancia. Esta vulnerabilidad está corregida en 1.123.43, 2.22.1 y 2.20.7.
