SCA: security update for onnx (GHSA-538c-55jv-c5g9)

high Tenable Self-Hosted Container Security Plugin ID 439673

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Open Neural Network Exchange (ONNX) is an open standard for machine learning interoperability. Prior to
version 1.21.0, the ExternalDataInfo class in ONNX was using Python’s setattr() function to load metadata
(like file paths or data lengths) directly from an ONNX model file. It didn’t check if the "keys" in the
file were valid. Due to this, an attacker could craft a malicious model that overwrites internal object
properties. This issue has been patched in version 1.21.0. (CVE-2026-34445)

Solution

Update the onnx library and its related packages to version 1.21.0 or later.
