Mitigation
This problem is only exposed when the user uses server-side prepared statement support (mysql_server_prepare=1), which is NOT default behavior and was turned off back for all drivers per MySQL AB decision in 2006 due to issues with server-side prepared statements in the server.
Use the default driver setting which uses emulated prepared statements.
