CVE-2026-13414

MediumCVSS 4.8/10Last modified Aug 28, 2026

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.
