Action Pack 是一个用于处理并响应 Web 请求的框架。在 Rails 8.1.0 至 8.1.4.1 版本期间，ActionDispatch::RemoteIp 会基于 Rack::Request#forwarded_for 来推导 request.remote_ip。而在 Rack 3 中，forwarded_for 方法会优先读取符合 RFC 7239 标准的 Forwarded 头，而非 X-Forwarded-For 头。 当反向代理将客户端地址追加到 X-Forwarded-For 头中，却原

Vulnerability Title
Action Pack: Possible IP spoofing in Action Dispatch RemoteIp
来源: CVE Program / CVE List V5
Vulnerability Description
Action Pack is a framework for handling and responding to web requests. From 8.1 until 8.1.4.1, Since Rails 8.1.0, ActionDispatch::RemoteIp derives request.remote_ip from Rack::Request#forwarded_for, which under Rack 3 reads the RFC 7239 Forwarded header in preference to X-Forwarded-For. When a reverse proxy appends the client address to X-Forwarded-For but passes a client-supplied Forwarded header through unchanged, request.remote_ip returns an address chosen by the client, and the IP spoofing check does not raise, because it compares only Client-Ip with the forwarded addresses. An unauthenticated attacker could therefore spoof request.remote_ip, possibly bypassing IP-based access controls and rate limits keyed on the client address (including the default by: of rate_limit), and falsifying the client address in logs. An application is affected if it meets all of these requirements: Runs Rails 8.1.0 through 8.1.4 with Rack 3. Under Rack 2.2, forwarded_for reads only X-Forwarded-For. Is served behind a proxy that does not remove or overwrite a client-supplied Forwarded header. Relies on request.remote_ip for access control, rate limiting, or auditing. The fix detects a spoofed Forwarded header only when the proxy also sets X-Forwarded-For. An application whose proxy passes a client-supplied Forwarded header through and sets no X-Forwarded-For remains exposed after upgrading, and should configure the proxy to remove or overwrite Forwarded, or apply the workaround below. This issue is fixed in version 8.1.4.1.
