The caddy-geo-ip (aka GeoIP) middleware through 0.6.0 for Caddy 2, when trustheader X-Forwarded-For is used, allows attackers to spoof their source IP address via an X-Forwarded-For header, which may bypass a protection mechanism (trustedproxy directive in reverse_proxy or IP address range restrictions).
