CVE-2022-20303

Local account-presence disclosure via missing permission check

Published Aug 11, 2022 · Updated Aug 3, 2024

Information disclosure in Android 13 ContentService allows local users to determine whether an account is present on the device. ContentService answers an account-presence query without enforcing the GET_ACCOUNTS permission that normally protects account information. User-level code can obtain this account-presence information without user interaction, but the documented impact is limited to local disclosure rather than account modification.
