Official description
PipesHub before 0.10.0 contains a rate limit bypass vulnerability in getClientIp() that allows unauthenticated attackers to evade per-IP throttling by spoofing X-Forwarded-For or X-Real-IP headers. Attackers can rotate header values to obtain fresh rate-limit buckets on authentication endpoints, enabling password spraying and OTP or password-reset email flooding.
