EPSS Percentile

0th

The Booking for Appointments and Events Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple Elementor widgets in versions up to and including 2.4.9. This is due to insufficient input sanitization and output escaping on the 'load_manually' parameter in the render() methods of classes. This makes it possible for authenticated attackers, with Contributor-level access and above who can use Elementor, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The vulnerability was partially patched in version 2.4.8.
