What is CVE-2026-6127?

The Elementor Website Builder plugin for WordPress has a vulnerability that allows stored cross-site scripting due to inadequate input sanitization of the _elementor_data meta field. This issue arises when the plugin processes form-encoded REST API requests without proper sanitization, leaving the door open for authenticated users with contributor-level access to inject malicious scripts. The unsanitized data can be stored and output through various widget components, creating a risk for users accessing affected pages.
