CVE-2022-20277

Installed-app disclosure via observable response discrepancy

Published Aug 11, 2022 · Updated Aug 3, 2024

Information disclosure in DevicePolicyManager in Google Cloud Android 13 allows local users to determine whether an app is installed. DevicePolicyManager exposes an observable response discrepancy when an app without package-query permission tests for another app's presence. A locally installed app needs no additional execution privileges or user interaction, and the disclosed fact is limited to app presence.
