CVE-2026-63632: Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. From 1.3.0 until 1.22.0,

ONNX (Open Neural Network Exchange, a standard format for sharing machine learning models) versions 1.3.0 through 1.22.0 have a bug where converting models to an older format can crash if certain input data doesn't have enough dimensions, because the code tries to read array positions that don't exist without checking first.
