Go to dashboardVikunja <= 2.5.0 does not apply the unconditional pre-auth per-IP rate limit (unauthRateLimit, default 10/60s) to /api/v2 public routes (login, register, password-reset token, oauth token). v1 twins are throttled, but v2 relies on the global limiter, which is off by default. A stock install allows unlimited password guessing, account enumeration and reset flooding. Fixed in 2.6.0.
