CVE-2026-27981— HomeBox has an Auth Rate Limit Bypass via IP Spoofing

HomeBox has an Auth Rate Limit Bypass via IP Spoofing

HomeBox is a home inventory and organization system. Prior to 0.24.0, the authentication rate limiter (authRateLimiter) tracks failed attempts per client IP. It determines the client IP by reading, 1. X-Real-IP header, 2. First entry of X-Forwarded-For header, and 3. r.RemoteAddr (TCP connection address). These headers were read unconditionally. An attacker connecting directly to Homebox could forge any value in X-Real-IP, effectively getting a fresh rate limit identity per request. There is a TrustProxy option in the configuration (Options.TrustProxy, default false), but this option was never read by any middleware or rate limiter code. Additionally, chi's middleware.RealIP was applied unconditionally in main.go, overwriting r.RemoteAddr with the forged header value before it reaches any handler. This vulnerability is fixed in 0.24.0.

过多认证尝试的限制不恰当

HomeBox 安全漏洞

HomeBox是SysAdmins Media开源的一个为家庭用户构建的库存和组织系统。 HomeBox 0.24.0之前版本存在安全漏洞，该漏洞源于身份验证速率限制器无条件读取并信任X-Real-IP等标头，且配置选项未生效，可能导致攻击者绕过速率限制。
