CMP - Coming Soon & Maintenance < 4.1.18 - Unauthenticated Maintenance Mode Disable via cmp_disable_comingsoon_ajax

Published Aug 27, 2026 · Updated Aug 27, 2026 · Assigned by WPScan

Description

The CMP WordPress plugin before 4.1.18 does not perform authorization checks on one of its AJAX actions and relies on a nonce that is skipped for certain (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.
