CVE-2022-20518

Local messaging disclosure via unchecked query parameters

Published Dec 16, 2022 · Updated Apr 18, 2025

SQL injection in Android 13 MmsSmsProvider allows local users to read restricted messaging database tables through a crafted provider query. The query method concatenates unchecked msg_id and thread_type values into extraSelection, allowing them to alter the generated SQL statement. User-level code can exploit the flaw without user interaction, but the effect is limited to local disclosure rather than data modification or service interruption.
