Descripción
The PowerPack Elementor Addons (Free Widgets, Extensions and Templates) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘cursor_url’ parameter in all versions up to, including, 2.9.4 due insufficient input sanitization output escaping. This makes it possible authenticated attackers, with Contributor-level access above, inject arbitrary web scripts pages that will execute whenever a user accesses an injected page.
