Is this vulnerability remotely exploitable?

Yes. The vulnerability is reachable over the network via the /signup.php endpoint, so any attacker who can access the web application can attempt exploitation.

Does an attacker need to be authenticated to exploit this?

Typically no. Signup functionality is usually exposed to unauthenticated users, meaning exploitation can often occur without prior login, provided /signup.php is publicly reachable.

What is the safest general fix pattern for this issue?

Replace any dynamically built SQL queries that use the Username parameter with parameterized queries or prepared statements, and pair this with strict validation rules on Username before it is sent to the database.
