      "value": "n8n is an open source workflow automation platform. Prior to 1.123.64, 2.29.8, and 2.30.1, the Git node clone operation allows an authenticated workflow user to swap a validated directory for a symlink before cloning, planting a crafted repository in the community node directory that loads as a custom JavaScript node after restart and executes arbitrary code on the server. This issue is fixed in versions 1.123.64, 2.29.8, and 2.30.1."

Antes de las versiones 1.123.64, 2.29.8 y 2.30.1, la operación de clonación del nodo Git permite a un usuario de flujo de trabajo autenticado intercambiar un directorio validado por un enlace simbólico antes de la clonación, insertando un repositorio manipulado en el directorio del nodo de la comunidad que se carga como un nodo JavaScript personalizado después del reinicio y ejecuta código arbitrario en el servidor. Este problema está solucionado en las versiones 1.123.64, 2.29.8 y 2.30.1."
