NVD Description

Note: Versions mentioned in the description apply only to the upstream onnx package and not the onnx package as distributed by Ubuntu. See How to fix? for Ubuntu:24.04 relevant fixed versions and status.

Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. Prior to version 1.21.0, there is an issue in onnx.load, the code checks for symlinks to prevent path traversal, but completely misses hardlinks because a hardlink looks exactly like a regular file on the filesystem. This issue has been patched in version 1.21.0.
