A code injection vulnerability has been identified in WongKinYiu YOLOv9 version 0.1, specifically within the ONNX Metadata Handler. The issue arises in the DetectMultiBackend.__init__ function, located in models/common.py. The vulnerability allows for remote exploitation by manipulating the 'names' and 'stride' arguments, leading to arbitrary code execution.
