DescriptionRara 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.
