0th
Gophish through 0.12.1 contains a rate limit bypass vulnerability that allows unauthenticated attackers to evade /login throttling by spoofing X-Forwarded-For or X-Real-IP headers. Attackers can send a different forwarded address per request so the limiter keyed on rewritten RemoteAddr never triggers, enabling unlimited password guessing and credential stuffing.
