CVE-2026-28500: Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability
CVE-2026-28500 is a high-severity flaw (CVSS 8.6) affecting onnx. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. In versions up to and including 1.20.1, a security control bypass exists in onnx.hub.load() due to improper logic in the repository trust verification mechanism. While the function is designed to warn users when loading models from non-official sources, the use of the silent=True parameter completely suppresses all security warnings and confirmation pro
