Description
The Responsive Starter Templates plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'responsive-ready-sites-elementor_page_import_process' AJAX action in versions 2.7.3 up to, and including, 3.5.4. This is due to the elementor_page_import_process() function checking only the edit_posts capability and not whether the user can edit the post given in the 'id' parameter. This makes it possible for authenticated attackers, with Contributor-level access and above, to replace the Elementor content of posts and pages they do not own, including other users' published pages, with template data loaded from a URL they supply.
