CVE-2026-34447 Details
Description
Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. Prior to version 1.21.0, there is a symlink traversal vulnerability in external data loading allows reading files outside the model directory. This issue has been patched in version 1.21.0.
A symlink traversal vulnerability has been identified in Open Neural Network Exchange (ONNX) versions prior to 1.21.0. This vulnerability allows external data loading to read files outside the model directory, leading to arbitrary file read and potential confidentiality breaches. The issue arises because the function responsible for resolving external data locations does not properly handle symlinks, allowing them to escape the intended directory confinement.
Users should update ONNX to version 1.21.0 or later, where this vulnerability has been patched.
