      "value": "react-dev-utils on Windows allows developers to run a local webserver for accepting various commands, including a command to launch an editor. The input to that command was not properly sanitized, allowing an attacker who can make a network request to the server (either via CSRF or by direct request) to execute arbitrary commands on the targeted system. This issue affects multiple branches: 1.x.x prior to 1.0.4, 2.x.x prior to 2.0.2, 3.x.x prior to 3.1.2, 4.x.x prior to 4.2.2, and 5.x.x prior to 5.0.2."

Las entradas a dicho comando no fueron sanadas debidamente, permitiendo a un atacante que puede enviar una petici\u00f3n de red al servidor (o mediante CSRF o bajo petici\u00f3n directa) para ejecutar comandos arbitrarios en el sistema objetivo. Este problema afecta a m\u00faltiples gamas: Las versiones 1.x.x anteriores a la 1.0.4, las 2.x.x anteriores a la 2.0.2, las 3.x.x anteriores a la 3.1.2, las 4.x.x anteriores a la 4.2.2 y las 5.x.x anteriores a la 5.0.2."
