Unlimited Elements For Elementor <= 2.0.20 - Authenticated (Subscriber+) Arbitrary Shortcode Execution

The Unlimited Elements For Elementor plugin for WordPress is vulnerable to Arbitrary Shortcode Execution in all versions up to, and including, 2.0.20. This is due to the use of do_shortcode() on user supplied input. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute arbitrary shortcodes registered on the site. The impact depends on which shortcodes the site has registered, so a site running a plugin whose shortcodes expose data or perform actions is affected more severely.

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Unlimited Elements for Elementor 2.0.21 closes this, and updating the plugin is the step that ends it.
