CVE-2026-119711
PipesHub before 0.10.0 Rate Limit Bypass via Spoofed X-Forwarded-For Header
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.
