IP2Location Country Blocker plugin for WordPress before 2.45.0 contains an access control bypass vulnerability that allows unauthenticated remote attackers to circumvent IP-based restrictions by forging the X-Real-IP HTTP header. Attackers can set the X-Real-IP header to an allowlisted IP address to bypass page, link, or site-wide access restrictions and access otherwise-blocked resources.
