CVE-2023-4140

Summary

The WP Ultimate CSV Importer plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 7.9.8 due to insufficient restriction on the 'get_header_values' function. This makes it possible for authenticated attackers, with minimal permissions such as an author, if the administrator previously grants access in the plugin settings, to modify their user role by supplying the 'wp_capabilities->cus1' parameter.
