• Go github.com/shift72/caddy-geo-ip: <= 0.6.0 (no fix yet)

Description

The caddy-geo-ip (aka GeoIP) middleware through 0.6.0 for Caddy 2, when trust_header 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 (trusted_proxy directive in reverse_proxy or IP address range restrictions).
