CVE-2026-55093 tract-nnef: integer overflow in NNEF `.dat` tensor parser yields an out-of-bounds read on model load

Tract is a tiny, no-nonsense, self-contained TensorFlow and ONNX inference toolkit. Prior to 0.21.16, 0.22.2, and 0.23.1, tract-nnef uses unchecked usize multiplication in nnef/src/tensors.rs readtensor for attacker-controlled tensor dimensions, the allocation size, and the reported tensor length...

CVE-2026-55093

Tract (a self-contained TensorFlow/ONNX inference toolkit by Sonos) is affected by an integer overflow in tract-nnef's read_tensor function that leads to an out-of-bounds heap read when loading a crafted NNEF model archive. The unchecked usize multiplication over attacker-controlled tensor dimens...

CVE-2026-55832

Tract is a tiny, no-nonsense, self-contained TensorFlow and ONNX inference toolkit. Prior to 0.21.17, 0.22.3, and 0.23.2, the tract-onnx crate passes the attacker-controlled externaldata location from an ONNX model through onnx/src/tensor.rs getexternalresources and joins the value to the model...

CVE-2026-55832

Tract (tract-onnx crate, a Rust inference toolkit for TensorFlow/ONNX) is vulnerable to arbitrary local file read when loading an untrusted ONNX model. The external_data location field is joined to the model directory via Path::join without rejecting absolute paths or .. components, so the defaul...

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...
