Technical description

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.

——0Rara One Click Demo Import plugin for WordPress before 1.3.5 contains an arbitrary file upload vulnerability that allows authenticated attackers with Administrator privileges to upload arbitrary PHP files by passing a false value to wp_handle_upload() that disables WordPress core's file type validation checks across all three file parameters in the process_uploaded_files() function. Attackers can upload a malicious PHP file to the uploads directory and execute it over HTTP to achieve remote code execution in the web server process, with the uploaded file persisting on disk even after plugin deactivation and leaving no media library record to evade standard integrity checks.14h CVE-2026-546115.5 MED
