Published Nov 7, 2023 · Updated Mar 6, 2025

Incorrect authorization in Samsung Email before 6.1.90.4 allows local users to read email data from the application's sandbox.

No privileges or user interaction are required after local execution is obtained on the Android device, and the reported consequence is limited to reading stored email data.
