CVE-2026-9281 Details
Description
The Master Addons For Elementor – Widgets, Extensions, Theme Builder, Popup Builder & Template Kits plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'jtlma_custom_js' Page Setting (Custom JS Extension) in all versions up to, and including, 3.1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The unfiltered_html capability check is only enforced during Elementor control registration (UI rendering) and not during the save process, enabling Author-level users to inject the jtlma_custom_js setting directly via a crafted POST request to admin-ajax.php?action=elementor_ajax, bypassing the UI-level restriction entirely.
A stored cross-site scripting vulnerability has been identified in the Master Addons For Elementor plugin for WordPress, affecting all versions through 3.1.0. The vulnerability arises from inadequate input sanitization and output escaping in the 'jtlma_custom_js' Page Setting, part of the Custom JS Extension. This flaw allows authenticated attackers with author-level access or higher to inject arbitrary web scripts into pages. The injected scripts execute when a user accesses the compromised page. The issue occurs because the unfiltered_html capability check is only applied during the registration of Elementor controls, not during the saving process. As a result, Author-level users can exploit this by sending a crafted POST request to admin-ajax.php?action=elementor_ajax, bypassing the user interface restrictions.
Users are advised to update the Master Addons For Elementor plugin to version 3.1.1 or later.
