ElementsKit Elementor addons <= 3.1.0 - Authenticated (Contributor+) Local File Inclusion via Onepage Scroll Module

The ElementsKit Elementor addons plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 3.1.0 via the generate_navigation_markup function of the Onepage Scroll module. This makes it possible for authenticated attackers, with contributor-level access and above, to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.
