Notes

ccdm94

it seems like the external_data field, which leads to the vulnerability, was only introduced in version 1.4.0 of onnx, as per information recovered from PR 678 and commit 51b6ecce (see https://github.com/onnx/onnx/releases/tag/v1.4.0 as well for more information). This means versions prior to version 1.4.0 are not vulnerable.
