PaddlePaddle PaddleX Preprocessor processors.py NormalizeImage.__init__ code injection

A flaw has been found in PaddlePaddle PaddleX up to 3.7.2. Affected by this vulnerability is the function NormalizeImage.__init__ of the file paddlex/inference/models/text_detection/processors.py of the component Preprocessor. This manipulation of the argument scale causes code injection. It is possible to initiate the attack remotely. The pull request to fix this issue awaits acceptance.
