7.4 · HIGHOverview
CVE-2026-27981 is a high-severity vulnerability affecting sysadminsmedia homebox. It was published on March 3, 2026 and has a CVSS 3.1 base score of 7.4 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.4, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from sysadminsmedia. Update homebox to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
