Miggo AIMiggo AIMiggo AIRoot Cause AnalysisThe vulnerability stems from how external_data paths were handled in check_tensor. The pre-patch code in onnx/checker.cc line 129 constructed paths via path_join without sanitizing entry.value(), allowing directory traversal. The fix introduced clean_relative_path to normalize paths and block '../' prefixes. The path_join function's role in combining paths without validation contributed to the vulnerability, though the primary flaw was the lack of sanitization in check_tensor's logic.
