Description

The Sina Extension for Elementor (Slider, Gallery, Form, Modal, Data Table, Tab, Particle, Free Elementor Widgets & Elementor Templates) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Sina Particle Layer widget in all versions up to, and including, 3.5.3 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. CVE-2024-35703 is likely a duplicate of this issue.
