CVE-2026-4803

The Royal Elementor Addons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'status' parameter in the wpr_update_form_action_meta AJAX action in all versions up to, and including, 1.7.1056. This is due to insufficient input sanitization and output escaping, combined with a publicly leaked nonce that allows unauthenticated access to the AJAX handler. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
