Summary
The Drag and Drop File Upload for Elementor Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.6.0 via the elementor_file_upload function. This is due to insufficient file type validation in the is_file_type_valid() function, which uses the attacker-controlled 'type' parameter as regex keys in the MIME allowlist, allowing blacklist bypass via a crafted extension that sanitize_file_name() later normalizes to a PHP extension. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.
