{"cve":"CVE-2026-55832","nvd":{"published":"2026-09-14T18:17:55.663","modified":"2026-09-30T19:57:08.043","status":"Deferred","description":"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/src/data_resolver.rs MmapDataResolver open an arbitrary local file and place the file contents into model tensors or inference output. Attacker-controlled offset and length fields can also select an out-of-range mapping slice and cause a denial of service, but the flaw does not write files or execute code. This issue is fixed in versions 0.21.17, 0.22.3, and 0.23.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:L","score":6.1},"cwes":["CWE-22"],"references":["https://github.com/sonos/tract/commit/5f994bcf3cec9b343830a975fedce177f9190d0f","https://github.com/sonos/tract/commit/85f4fac23e43d417782e8ed9f9465be8474f5c98","https://github.com/sonos/tract/commit/8fdacbd7abe4e6f929cadfe52e7f69e2227c0632","https://github.com/sonos/tract/releases/tag/0.21.17","https://github.com/sonos/tract/releases/tag/0.22.3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-55832","score":0.00194,"percentile":0.08964,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-h668-6x6g-f8r5","url":"https://osv.dev/vulnerability/GHSA-h668-6x6g-f8r5","summary":"tract: Arbitrary file read via unsanitized ONNX external_data `location` (path traversal) on model load in tract-onnx","modified":"2026-09-10T03:50:49.736690654Z","packages":[{"ecosystem":"crates.io","name":"tract-onnx","purl":"pkg:cargo/tract-onnx","ranges":["<0.21.17"],"fixed":["0.21.17"]},{"ecosystem":"crates.io","name":"tract-onnx","purl":"pkg:cargo/tract-onnx","ranges":[">=0.22.0 <0.22.3"],"fixed":["0.22.3"]},{"ecosystem":"crates.io","name":"tract-onnx","purl":"pkg:cargo/tract-onnx","ranges":[">=0.23.0 <0.23.2"],"fixed":["0.23.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
