Is this vulnerability remotely exploitable?

Yes. An attacker with network access to the login page or API can exploit the vulnerable username parameter remotely, without needing prior authentication.

What level of access does an attacker need to exploit this issue?

Only unauthenticated access to the application's login interface is required. The attacker does not need any existing account or special permissions.

What is the safest general fix pattern for this vulnerability class?

Refactor all authentication-related database operations to use parameterized queries or ORM parameter binding exclusively, and remove any string concatenation of user input in SQL. Combine this with strict validation of login inputs and minimal database privileges.
