Balance disclosure via unauthenticated lock-screen QR scan
Published Mar 4, 2021 · Updated Aug 3, 2024
Improper access control in Samsung Pay mini before 4.0.14 allows physically proximate attackers to view balance data from the lock screen. The lock-screen QR scanner accepts a specific QR code and displays the associated balance without first requiring device unlock. Exploitation requires physical access to a configured device; the disclosed confidentiality impact is limited to balance information.
