That code joins the base directory with a user given string without checking if the final path is located outside the base directory. This vulnerability cannot be used to read the contents of files but could in theory be used to trigger a denial of service for the program. This issue has been addressed in version 3.1.37."}, {"lang": "es", "value": "GitPython es una biblioteca de python utilizada para interactuar con repositorios Git.
