If an attacker can control the content of the YAML configuration file passed to the --run_config parameter, arbitrary code can be executed during deserialization. This can lead to full system compromise. The vulnerability is triggered when a malicious YAML file is loaded, allowing the execution of arbitrary Python commands such as os.system(). It is recommended to upgrade PyYAML to version 5.4 or higher, and to use yaml.safe_load() to mitigate the issue."}, {"lang": "es", "value": "Existe una vulnerabilidad de ejecuci\u00f3n remota de c\u00f3digo (RCE) en el proyecto ms-swift versi\u00f3n 3.3.0 debido a una deserializaci\u00f3n insegura en tests/run.py mediante yaml.load() de la librer\u00eda PyYAML (versiones = 5.3.1).
