Cross-user image disclosure via unchecked Autofill URIs
Published Feb 16, 2024 · Updated Nov 21, 2024
Information disclosure in Google Android 11 through 14 allows local users to view another user's images through the Autofill save UI. SaveUi.applyCustomDescription accepts icon content URIs from an Autofill service without verifying that the service can access the referenced images. A malicious local app with ordinary execution privileges can abuse the framework as a confused deputy without user interaction, exposing image content across user boundaries.
