Published Apr 18, 2026 · updated Jun 17, 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 AJAX action. This is due to the function only checking for the capability (available to Editors and above) instead of (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 ( ), resulting in remote code execution. Due to the lack of a nonce for Editors, they are unable to exploit this vulnerability.
