CVE-2026-12470, 22 Sep 2026
The CMP - Coming Soon & Maintenance Plugin by NiteoThemes plugin for WordPress is vulnerable to unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the 'cmp_ajax_import_settings' AJAX action in all versions up to, and including, 4.1.17. This makes it possible for authenticated attackers, with Editor-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access to a vulnerable site. CVE record
CVE-2026-13414, 27 Aug 2026
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. CVE record
CVE-2026-13415, 27 Aug 2026
The CMP WordPress plugin before 4.1.18 does not enforce an option-name allow-list when importing settings via one of its AJAX actions, allowing users with the Editor role (when the administrator has granted the Editor role access to the CMP WordPress plugin before 4.1.18's admin-bar controls) to update arbitrary WordPress options, including options that lead to privilege escalation to Administrator. CVE record
CVE-2026-13416, 27 Aug 2026
The CMP WordPress plugin before 4.1.18 does not sanitise and escape a settings value before outputting it on the coming-soon page, allowing users with the Editor role (when the administrator has granted the Editor role access to the CMP WordPress plugin before 4.1.18's admin-bar controls) to inject arbitrary web scripts that execute when a visitor views the page. CVE record
CVE-2026-6518, 18 Apr 2026
The CMP - Coming Soon & Maintenance Plugin by NiteoThemes plugin for WordPress is vulnerable to arbitrary file upload and remote code execution in all versions up to, and including, 4.1.16 via the `cmp_theme_update_install` AJAX action. This is due to the function only checking for the `publish_pages` capability (available to Editors and above) instead of `manage_options` (Administrators only), combined with a lack of proper validation on the user-supplied file URL and no verification of the downloaded file's content before extraction. This makes it possible for authenticated attackers, with Administrator-level access and above, to force the server to download and extract a malicious ZIP file from a remote attacker-controlled URL into a web-accessible directory (`wp-content/plugins/cmp-premium-themes/`), resulting in remote code execution. Due to the lack of a nonce for Editors, they are unable to exploit this vulnerability. CVE record
CVE-2023-2159, 9 Jun 2023
The CMP - Coming Soon & Maintenance plugin for WordPress is vulnerable to Maintenance Mode Bypass in versions up to, and including, 4.1.7. A correct cmp_bypass GET parameter in the URL (equal to the md5-hashed home_url in the default setting) allows users to visit a site placed in maintenance mode thus bypassing the plugin's provided feature. CVE record
CVE-2023-1263, 7 Mar 2023
The CMP - Coming Soon & Maintenance plugin for WordPress is vulnerable to Information Exposure in versions up to, and including, 4.1.6 via the cmp_get_post_detail function. This can allow unauthenticated individuals to obtain the contents of any non-password-protected, published post or page even when maintenance mode is enabled. CVE record
CVE-2022-0188, 14 Feb 2022
The CMP WordPress plugin before 4.0.19 allows any user, even not logged in, to arbitrarily change the coming soon page layout. CVE record

What to do if you run CMP

If you run CMP, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.

If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
