CVE-2023-40133

Cross-user image disclosure via unchecked RemoteViews URIs

Published Oct 27, 2023 · Updated Sep 9, 2024

Information disclosure in Android 11, 12, 12L, and 13 allows local users to view another user's images through Autofill RemoteViews. DialogFillUi and related Autofill UI code rendered URIs from a FillResponse without verifying that the current user had permission to read them. A malicious Autofill provider can therefore use a cross-user content URI to expose images without user interaction or added execution privileges.
