Description
BlueprintUE Self-Hosted Edition 4.2.0 before 4.3.4 contains a login rate limit bypass vulnerability in LoginMiddleware.php that keys failed-login counters on case-sensitive usernames. Unauthenticated attackers can vary username casing against case-insensitive MySQL lookups to get extra attempts and brute-force passwords past the per-account lockout.
