Last modified
CVE-2023-50463 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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).. EPSS estimates a 0.66% chance of exploitation in the next 30 days.
