Sensitive-data disclosure via undisclosed cleartext storage

Published Aug 10, 2026 · Updated Aug 10, 2026

Cleartext storage in Samsung Smart Switch before 3.7.72.6 allows adjacent attackers to access sensitive data during device transfers. Samsung identifies the issue only as exposed sensitive information retained in cleartext and does not disclose the storage location, data fields, or access path. Exploitation requires an adjacent attacker and passive user involvement; the reported consequence is disclosure, not modification or service interruption.
