go-chi/chi through 5.2.1 contains an IP spoofing vulnerability in the RealIP middleware (middleware/realip.go). The realIP() function reads client-controlled headers (True-Client-IP, X-Real-IP, and X-Forwarded-For) and overwrites r.RemoteAddr without verifying that the request originated from a trusted proxy. Attackers can supply arbitrary IP addresses in these headers to bypass IP-based access controls, evade rate limiting and geo-IP restrictions, and pollute audit logs. Fixed in 5.3.0.

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-8d9ba295e0 advisory.

    Update the bundled github.com/go-chi/chi/v5 to v5.3.1, which is outside the     range affected by CVE-2026-72815, CVE-2026-72816 and CVE-2026-72817 (IP     spoofing via chi's RealIP middleware).

    opkssh bundles only chi's root router package and never the affected     middleware package, so the vulnerable code was not actually shipped in any     opkssh build.
