CVE-2025-13453

Physical data disclosure via missing encryption

Published Jan 14, 2026 · Updated Jan 14, 2026

Missing encryption in Lenovo ThinkPlus FU100, FU200, TSD303, and TU800 Gen 1 allows physically proximate attackers to read stored data. The drive firmware fails to encrypt sensitive stored data, but Lenovo has not disclosed the affected storage path, key handling, or read procedure. Physical possession is required; the reported consequence is confidentiality loss only, with no integrity or availability impact.
