Duplicate Advisory
This advisory has been withdrawn because it is a duplicate of GHSA-j6qf-3m9c-vwj3. This link is maintained to preserve external references.
Original Description
In the Golang Chi web framework, the ClientIPFromXFF middleware skips any X-Forwarded-For entry in a configured trusted CIDR but never verifies that the direct TCP peer in http.Request.RemoteAddr belongs to that CIDR. A client that can reach the Go server directly can therefore append a trusted-looking proxy address and choose the client IP returned by middleware.GetClientIP.
This issue affects chi before 5.4.0.
