Dynific Addons for Elementor (formerly Anywhere Elementor) <= 1.3.0 - Unauthenticated Arbitrary Shortcode Execution via Comment Content via do_shortcode() over rendered template buffer

The The Dynific Addons for Elementor (formerly Anywhere Elementor) plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 1.3.0 This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes. Exploitation requires the target site to have a public post rendered through an AE template that includes the AE Post Comments widget, and for the attacker's comment to be visible on that page — a barrier removed once the attacker has a previously approved comment or when comment moderation is relaxed.

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: 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: Dynific Addons for Elementor (formerly Anywhere Elementor) 1.3.1 closes this, and updating the plugin is the step that ends it.
