Description
The InfiniteWP Client WordPress plugin before 1.13.6 does not properly verify the site-connection state and the authenticity of requests to its remote-management endpoint on WordPress Multisite installations, allowing unauthenticated attackers to bind their own key, hijack an administrator session, and take over the entire network, leading to remote code execution.
