Amelia Elementor widgets permit contributor stored XSS

Booking for Appointments and Events Calendar through 2.4.9 fails to sanitize and escape the load_manually parameter in the render() methods of multiple Elementor widgets. A contributor who can use Elementor can store JavaScript in a page and execute it for anyone who visits. Version 2.4.8 only partially patched the issue.

What to do

Update, patch or deactivate.

No fully fixed release is confirmed in the authoritative export; 2.4.9 remains affected. Restrict Elementor editing or deactivate the affected widgets pending a complete vendor fix. The application-level fix must validate load_manually and escape it for every widget render context.

No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Source record

Technical description

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.
