CVE-2026-91015 Details
Description
The Master Addons for Elementor WordPress plugin before 3.1.9 does not perform an authorization check on the AJAX action that deactivates its Popup Builder popups, relying only on a nonce that is publicly output to every visitor, allowing unauthenticated attackers to permanently disable any popup on the site.
A vulnerability exists in the Master Addons for Elementor WordPress plugin in versions prior to 3.1.9. The issue arises because the plugin does not implement proper authorization checks on the AJAX action responsible for deactivating popups created with its Popup Builder. Instead, it relies solely on a nonce that is publicly accessible to all visitors. This flaw allows unauthenticated attackers to permanently disable any popup on the site.
Users are advised to update the Master Addons for Elementor WordPress plugin to version 3.1.9 or later.
