CVE-2026-55832: Tract is a tiny, no-nonsense, self-contained TensorFlow and ONNX inference toolkit
CVE-2026-55832 is a medium-severity flaw (CVSS 6.1) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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 external_data location from an ONNX model through onnx/src/tensor.rs get_external_resources and joins the value to the model directory without rejecting absolute paths or parent directory components. Loading an untrusted model through model_for_path can therefore make onnx/sr
