How broadly exploitable is this vulnerability?

Any attacker with network access to a vulnerable MyTube instance can exploit this issue, as it does not require valid credentials or an existing session; simply omitting the authentication cookie can be sufficient to bypass protection on affected routes.

Does an attacker need an existing account or any special privileges?

No existing account is required. The flaw allows unauthenticated users—without any login—to reach routes that should only be accessible to authenticated or administrative users.

What is the safest general fix pattern for developers?

Implement a strict fail-closed authorization middleware: explicitly check for a valid authenticated user and required role, and immediately return an error (such as 401 Unauthorized or 403 Forbidden) when these conditions are not met, rather than allowing requests to fall through to downstream handlers.
