DescriptionCVE.org

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.

AnalysisAI

IP-based geo-restriction bypass in IP2Location Country Blocker for WordPress (all versions before 2.45.0) allows unauthenticated remote attackers to access restricted pages, links, or entire sites by forging the X-Real-IP HTTP header with an allowlisted IP address. The plugin resolves the client's country from this user-controlled header without validating it against the actual TCP connection source, making any IP-based access control rule trivially defeatable. …
