Summary
The Master Addons for Elementor – Elementor Addons, Widgets, Mega Menu Builder, Popup Builder, Widget Builder & Template Kits plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.1.9 via the upload_template_kit function. This is due to incorrect authorization on the upload_template_kit() AJAX handler, which requires only upload_files capability instead of the manage_options required by all sibling handlers, combined with missing per-entry file type filtering after ZIP extraction. This makes it possible for authenticated attackers, with editor-level access and above, to upload files that may be executable, which makes remote code execution possible. Editors can satisfy the nonce requirement because the required nonces are localized on the standard Pages list screen, which is accessible to any user with the edit_pages capability.
