Vulnerability from github – Published: 2026-06-25 18:18 – Updated: 2026-06-25 18:18

Summary

chi Middleware Vulnerable to Potential IP Spoofing via `X-Forwarded-For` Header in `Request.RemoteAddr` Resolution

Details

Summary

The vulnerability allows the Request.RemoteAddr to be spoofed when determining the request source IP via the X-Forwarded-For header. This could result in misidentification of the request source and potentially compromise access control and logging integrity.

Details

Currently, the RealIP() implementation splits the X-Forwarded-For header by , and uses the first IP. https://github.com/go-chi/chi/blob/v5.1.0/middleware/realip.go#L50-L54

However, relying on the first IP in the X-Forwarded-For header is insecure because it can be manipulated by attackers to falsify the source IP.

Malicious Case: 1. A malicious client sends a request with a forged IP in the X-Forwarded-For header: X-Forwarded-For: <forged-ip> 2. The proxy appends the actual client’s IP and forwards the request: X-Forwarded-For: <forged-ip>,<client-ip> 3. If the server always uses the first IP, it becomes vulnerable to IP spoofing.

Ideally, the implementation should verify IPs starting from the end of the X-Forwarded-For header value, skipping trusted IPs within the system, and using the first untrusted IP as the actual client IP.

For example, the labstack/echo web framework processes the X-Forwarded-For header by checking IPs from the end, skipping trusted IPs, and using the first untrusted IP as the client's ip. https://github.com/labstack/echo/blob/v4.13.2/ip.go#L261-L273

PoC

1. Run the Go application with the following code:

package main

import (
    "fmt"
    "log"
    "net/http"

    "github.com/go-chi/chi/v5/middleware"
)

func main() {
    // Set handler to print the remote address
    handler := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintln(
            w,
            fmt.Sprintf("remote addr: %s (want 192.0.2.1)", r.RemoteAddr),
        )
    })
    // Use RealIP middleware
    log.Fatal(http.ListenAndServe(":8080", middleware.RealIP(handler)))
}

2. Send a request to the server using curl with a manipulated X-Forwarded-For header:

$ curl localhost:8080 -H 'X-Forwarded-For: 192.0.2.2, 192.0.2.1'
remote addr: 192.0.2.2 (want 192.0.2.1)

Impact

This vulnerability can lead to a request source IP spoofing issue, which may allow attackers to bypass access controls or falsify request logs. It primarily affects systems that rely on X-Forwarded-For to determine the actual client IP, particularly in scenarios where intermediary proxies or load balancers are involved.

Severity

7.7 (High)
