 "title": "File Manager Pro – Filester <= 2.1.4 - Authenticated (Administrator+) Missing Authorization to Arbitrary Plugin Installation and Activation",
 "description": "The Filester plugin for WordPress is vulnerable to unauthorized plugin installation and activation via the yay_recommended_upgrade_plugin and yay_recommended_activate_plugin AJAX actions in all versions up to, and including, 2.1.4 due to a missing capability check; the handlers only verify a nonce. The nonce is exposed on the Recommended Plugins page, which requires manage_options. On multisite installations this makes it possible for authenticated site administrators, who lack the install_plugins and activate_plugins capabilities, to install plugins from arbitrary package URLs and activate them. This can lead to remote code execution.",
