WordPress Plugin Vulnerabilities
CMP - Coming Soon & Maintenance < 4.1.18 - Unauthenticated Maintenance Mode Disable via cmp_disable_comingsoon_ajax
Description
The plugin does not perform authorization checks on one of its AJAX actions and relies on a nonce that is skipped for certain themes (and exposed to anonymous visitors on others), allowing unauthenticated attackers to disable the site's maintenance/coming-soon mode under a non-default countdown configuration.
