The Management App for WooCommerce – Order notifications, Order management, Lead management, Uptime Monitoring plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the nouvello_upload_csv_file function in all versions up to, and including, 1.2.0. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
