CVE-2026-27981

HomeBox vulnerability CVE-2026-27981 allows an attacker to bypass authentication rate limiting by spoofing client IPs via X-Real-IP and manipulating X-Forwarded-For, since the authRateLimiter reads these headers and r.RemoteAddr unconditionally, with RealIP middleware overwriting the remote addre...
