CVE-2022-40825Network attack vector

SQL injection via unfiltered database field names

Published Oct 7, 2022 · Updated Aug 3, 2024

The disputed SQL injection claim for CodeIgniter 3.0 through 3.1.13 describes attackers altering queries through database field names. When application code passes client input as a field name, where_in() in system/database/DB_query_builder.php does not filter the identifier before adding it to the SQL query. The report itself makes exploitation conditional on a developer incorrectly accepting query fields from a client, so affected deployments depend on application-specific usage.
