Recurring patterns

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

Auth Bypass: Historically, connection ports could be accessed without proper authentication. Unauthorized users on the same network or host could connect directly to the IPython kernel and execute arbitrary code. The fix requires reading connection details and HMAC keys securely from a JSON connection file.

Broken Cryptography: Failing to sign messages allowed injection attacks against the kernel-client channel. Ensuring HMAC message signing is enabled by default is critical to maintaining communication integrity.
