Technical details
The Master Addons For Elementor plugin is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping in the 'jtlma_custom_js' Page Setting. While the plugin attempts to enforce 'unfiltered_html' capability checks during UI rendering, it fails to validate these permissions during the actual save process. An authenticated attacker with Author-level access can bypass UI restrictions by sending a crafted POST request to 'admin-ajax.php?action=elementor_ajax' to inject arbitrary JavaScript. This script is then stored and executed in the context of any user who views the compromised page. The issue is present in all versions up to and including 3.1.0.
