Attackers can supply a pickle-backed dataset that is processed by Pandas._generate_tables via pandas.read_pickle() without validation, so when a victim calls datasets.load_dataset(\"pandas\", data_files=...), the embedded __reduce__ payload executes code with the victim process's privileges.","published":"2026-10-23T16:16:52.000","modified":"2026-10-23T16:16:52.000","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/huggingface/datasets/pull/8879","label":"huggingface/datasets#8879"},"references":[{"type":"WEB","url":"https://github.com/SaiTeja-Erukude/CVE-2026-57845-hf-datasets-rce"},{"type":"WEB","url":"https://github.com/huggingface/datasets/pull/8879"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/hugging-face-datasets-pickle-deserialization-rce-via-pandas-builder"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-23T16:16:52.000"}}
