Description
The DevKit Pro plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 2.3.0. This is due to a missing capability check and missing nonce validation in the DPDEV_install_themes_func() function registered on the wp_ajax_DPDEV_install_themes action. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install arbitrary theme ZIP packages containing PHP files that are extracted into the web-accessible wp-content/themes/ directory, which may make remote code execution possible.
