Advisory
Source description from Wordfence Intelligence.
The WP Ultimate CSV Importer plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on several functions like upload_function(), display_log(), download_log(), display_csv_values(), etc... in versions up to 6.4.1. This makes it possible for authenticated attackers with minimal permissions, such as subscribers, to perform many unauthorized actions and retrieve sensitive data.
