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.","severity":"high","score":8.7,"published":"2026-10-23T15:14:20.497Z","modified":"2026-10-27T10:14:11.559Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://github.com/SaiTeja-Erukude/CVE-2026-57845-hf-datasets-rce","https://github.com/huggingface/datasets/pull/8879","https://www.vulncheck.com/advisories/hugging-face-datasets-pickle-deserialization-rce-via-pandas-builder"],"sources":[{"name":"CVE","id":"CVE-2026-57845","modified":"2026-10-27T10:14:11.559Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-57845"}],"assessments":[{"source":"VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7},{"source":"VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T19:15:31.108Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
