Is this vulnerability remotely exploitable?

Yes. Any remote attacker who can reach the exposed password verification endpoints can exploit the vulnerability without prior authentication by sending repeated invalid login requests.

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

The attacker only needs network access to the MyTube instance's public authentication endpoints. No valid account, credentials, or administrative privileges are required.

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

The most robust fix is to redesign brute-force protection so that failed-attempt counters and cooldown timers are scoped to individual identities or sources (e.g., per-account, per-IP, or per-session), and to avoid any globally shared lockout state that can impact unrelated users. Additional measures like upstream rate limiting and CAPTCHAs can further reduce abuse potential.
