CVE-2023-45774

Cross-user image disclosure via unvalidated shortcut URI

Published Dec 4, 2023 · Updated Dec 2, 2024

Confused-deputy flaw in Android 11 through 14 allows local users to view another user's shortcut image through ShortcutService. ShortcutService.fixUpIncomingShortcutInfo accepts a URI-based shortcut icon without verifying that the calling UID has read access to its content URI. A low-privileged app can abuse the system service without user interaction, crossing Android user boundaries to disclose image content; no code execution is required.
