EUVD-2026-9346

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...

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...

cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.27.0, a vulnerability allows attacker-controlled HTTP headers to influence server-visible metadata, logging, and authorization decisions. An attacker can supply X-Forwarded-For or X-Real-IP headers which...

CVE-2025-51663

FileCodeBox (up to 2.2) includes an IP rate-limiting flaw in the IPRateLimit implementation that lets remote attackers bypass ip-based rate limits and failed attempt restrictions by forging X-Real-IP and X-Forwarded-For headers. This can enable DoS or brute-force sharing code attempts. Affected c...
