Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Information Disclosure: Passing a numeric value instead of a string to the frame sender triggers the deprecated and unsafe `new Buffer(number)` behavior, which allocates uninitialized memory containing sensitive raw server data and transmits it to the client.

Information Disclosure: The use of the deprecated `new Buffer` constructor across the driver can lead to unexpected memory allocation bugs if inputs are not strictly validated, requiring migration to safer allocation APIs.
