Borderless – Widgets, Elements, Templates and Toolkit for Elementor & Gutenberg <= 1.5.9 - Authenticated (Administrator+) Remote Code Execution
The Borderless – Widgets, Elements, Templates and Toolkit for Elementor & Gutenberg plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 1.5.9 via the 'write_config' function. This is due to a lack of sanitization on an imported JSON file. This makes it possible for authenticated attackers, with Administrator-level access and above, to execute code on the server.
