Vulnerability Description
The CMP – Coming Soon & Maintenance WordPress plugin before 4.1.20 does not correctly restrict access to the site while maintenance/coming-soon mode is enabled, allowing unauthenticated visitors to bypass the coming-soon page and reach the otherwise hidden site, including hidden published pages, by shaping the request so it is mistaken for a login request.
