Better Elementor Addons Stored Cross-Site Scripting Vulnerability in WordPress

A stored cross-site scripting vulnerability has been identified in the Better Elementor Addons plugin for WordPress, affecting all versions through 1.5.4. The issue arises in the Slider widget, where inadequate input sanitization and output escaping on user-supplied attributes allow authenticated attackers with contributor-level access or higher to inject arbitrary web scripts. These scripts execute when a user accesses the compromised page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.
