CVE-2026-9281
MediumCVSS 6.4Summary
The Master Addons For Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via the 'jtlma_custom_js' Page Setting. Authenticated attackers with author-level access can inject arbitrary web scripts that will execute whenever a user accesses the injected page.
Risk Assessment
This vulnerability could lead to serious security breaches, allowing attackers to hijack user sessions or steal data. All users visiting the infected pages are at risk.
Recommendation
It is recommended to update the plugin to the latest version to mitigate this vulnerability. Additionally, implementing further security checks for users with author-level access is advisable.
Original NVD description (English source)
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.
