Attackers can craft malicious model files with invalid node references that trigger out-of-bounds writes at attacker-chosen offsets in the leaf_depth_ buffer during feature contribution computation.","published":"2026-09-16T20:32:43.282Z","modified":"2026-09-16T20:32:43.282Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"REPORT","url":"https://github.com/lightgbm-org/LightGBM/issues/7357"},{"type":"WEB","url":"https://github.com/lightgbm-org/LightGBM"},{"type":"WEB","url":"https://github.com/lightgbm-org/LightGBM/blob/v4.6.0/include/LightGBM/tree.h#L691-L698"},{"type":"WEB","url":"https://github.com/lightgbm-org/LightGBM/blob/v4.6.0/src/io/tree.cpp#L750-L766"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/lightgbm-through-4.7.0-out-of-bounds-write-via-crafted-model"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T20:32:43.282Z"}}
