NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-github-go-chi-chi package and not the golang-github-go-chi-chi package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

go-chi/chi versions 0.9.0 before 5.3.0 contains an IP spoofing vulnerability in the RealIP middleware, which resolves the request source IP (Request.RemoteAddr) using the first IP in the X-Forwarded-For header without validating trusted proxies. A malicious client can prepend a forged IP as the first value of the X-Forwarded-For header to spoof the request source IP, potentially bypassing access controls or falsifying request logs.
