SnakeYAML allows to unmarshal data to a Java type By using the YAML tag. Unmarshalling untrusted data can lead to security flaws of RCE."

SnakeYAML permite desglosar datos a un tipo Java mediante el uso de la etiqueta YAML. Descomponer datos no seguros puede conllevar a fallos de seguridad de RCE."
