Cross-user image disclosure via unchecked RemoteViews URIs
Published Oct 27, 2023 · Updated Sep 9, 2024
Information disclosure in Google Android 11 through 13 allows local users to view another user's images through a malicious Autofill provider. FillUi rendered URI-bearing RemoteViews supplied by an Autofill provider without checking whether each URI belonged to the active user. A locally installed malicious Autofill provider is required; exploitation needs neither further execution privileges nor user interaction and exposes cross-user image content.
