CVE-2022-20298

Local account-existence disclosure via missing permission check

Published Aug 11, 2022 · Updated Aug 3, 2024

Information disclosure in ContentService in Google Cloud Android 13 allows local users to determine whether an account exists on the device. ContentService checks for an on-device account without enforcing the permission that should restrict that query. A locally executing user-level process needs no user interaction and learns only account-existence information.
