No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The Royal Addons for Elementor WordPress plugin before 1.7.1066 does not correctly sanitise custom widget markup before writing it to a file that is later executed, allowing users with the manage_options capability (and, on WordPress Multisite, non-super subsite administrators who do not otherwise hold code-execution capabilities) to execute arbitrary PHP code.
