CVE-2026-92786

CVE-2026-92786 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. LightGBM through 4.7.0 fails to validate child and split array values when parsing text models, allowing attackers to write out-of-bounds memory during SHAP prediction. 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.. EPSS estimates a 0.19% chance of exploitation in the next 30 days.
