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...

Linux Distros Unpatched Vulnerability : CVE-2026-72817

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

CVE-2026-72816: Authentication Bypass by Spoofing

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: Insufficient Verification of Data Authenticity

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 fir...

github.com/go-chi/chi: go-chi/chi: IP Spoofing via RealIP Middleware allows bypassing access controls

A flaw was found in the go-chi/chi RealIP middleware. This vulnerability allows a remote attacker to perform IP spoofing by supplying arbitrary IP addresses in client-controlled headers. This can lead to bypassing IP-based access controls, evading rate limiting and geo-IP restrictions, and...

github.com/go-chi/chi/middleware: go-chi/chi: IP spoofing via X-Forwarded-For header manipulation

A flaw was found in the go-chi/chi component. The RealIP middleware, responsible for resolving the request source IP, does not properly validate trusted proxies when processing the X-Forwarded-For header. A remote attacker can exploit this by prepending a forged IP address to the X-Forwarded-For...
