A YAML parser can execute arbitrary Python commands resulting in command execution because load is used where safe_load should have been used. An attacker can insert Python into loaded YAML to trigger this vulnerability."

Un analizador sint\u00e1ctico de YAML puede ejecutar comandos Python arbitrarios. Esto resulta en una ejecuci\u00f3n de comandos, ya que se emplea load en lugar de safe_load. Un atacante puede insertar c\u00f3digo python en el YAML cargado para provocar esta vulnerabilidad."
