CVE-2026-44791

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 bypass the patch for CVE-2026-42232 in the XML node. When combined with other nodes, this could lead to RCE on the n8n host. 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 eludir el parche para CVE-2026-42232 en el nodo XML. Cuando se combina con otros nodos, esto podría conducir a RCE en el host de n8n. Esta vulnerabilidad se corrige en 1.123.43, 2.22.1 y 2.20.7.
