GHSA-H668-6X6G-F8R5 tract: Arbitrary file read via unsanitized ONNX external_data `location` (path traversal) on model load in tract-onnx

Summary tract the tract-onnx crate resolves an ONNX tensor's external-data location by joining it onto the model directory without any sanitization. Because location comes from the untrusted .onnx file, a malicious model can make tract open and read an arbitrary local file at load time, with the...

Security Bulletin: IBM Watson Speech Services Cartridge is vulnerable to a TOCTOU vulnerability in ONNX [GHSA-q56x-g2fj-4rj6]

Summary IBM Watson Speech Services Cartridge is vulnerable to a TOCTOU vulnerability in ONNX, due to multiple issues in the saveexternaldata method which introduce an arbitrary file read/write on any system GHSA-q56x-g2fj-4rj6. ONNX is used in our speech runtimes. This vulnerabilitiy has been...

Time-of-check Time-of-use (TOCTOU) Race Condition

Overview onnx is an Open Neural Network Exchange Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition through the saveexternaldata function. An attacker can overwrite arbitrary files or inject data into sensitive locations by exploiting a race...

CVE-2026-34445 ONNX: Malicious ONNX models can crash servers by exploiting unprotected object settings.

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...

Directory Traversal

Overview onnx is an Open Neural Network Exchange Affected versions of this package are vulnerable to Directory Traversal as the externaldata field of the tensor proto can have a path to the file which is outside the model current directory or user-provided directory, for example...
