CVE-2026-72816 go-chi chi before 5.3.0 IP Spoofing via RealIP Middleware

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...

CVE-2026-72817

The CVE affects go-chi/chi up to version 0.9.0 before 5.3.0, where the RealIP middleware resolves the source IP (Request.RemoteAddr) from the first IP in X-Forwarded-For without validating trusted proxies. An attacker can insert a forged value as the first IP, enabling IP spoofing that may bypass...

CVE-2026-72815

The CVE-2026-72815 affects go-chi chi v5.2.1 up to, but not including, v5.3.0. The RealIP middleware blindly trusts the leftmost value of X-Forwarded-For, enabling an attacker to bypass IP-based ACLs and rate limits and forge log entries by spoofing the IP address. The issue is fixed in v5.3.0. R...
