CVE-2026-9281: Master Addons For Elementor Stored XSS in jtlma_custom_js

CVE-2026-9281 · Severity: medium · CVSS 6.4 · Published 2026-06-06

Executive brief

The Master Addons for Elementor plugin for WordPress, which provides additional design tools for website builders, contains a security flaw. This vulnerability allows users with 'Author' level access to inject malicious scripts into website pages. When other visitors or administrators view these pages, the scripts can execute, potentially leading to unauthorized actions or data theft.

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.
