CVE-2022-42535

Local message disclosure via query parameter concatenation

Published Dec 16, 2022 · Updated Apr 17, 2025

SQL injection in Android 13 MmsSmsProvider allows local users to read restricted messaging tables through a crafted content query. The query method concatenates unchecked msg_id and thread_type values into extraSelection, allowing injected SQL to escape the intended filter. A user-executed app is required, but no user interaction is needed; impact is limited to local disclosure of protected SMS or MMS data.
