CVE-2023-30704

Downloaded-file disclosure via unauthenticated Secret Mode access

Published Aug 10, 2023 · Updated Oct 4, 2024

Improper authorization in Samsung Internet before 22.0.0.35 allows physically proximate attackers to read Secret Mode downloads. The file-access logic exposes files downloaded in Secret Mode without enforcing user authentication; Samsung has not disclosed the affected function or code path. Physical access to an affected mobile device is required, and the reported consequence is confined to disclosure of downloaded files.
