SecuPress Free < 2.3.10 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Plugin Installation

Description

The SecuPress Free — WordPress Security plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'secupress_reinstall_plugins_admin_ajax_cb' function in all versions up to, and including, 2.3.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install arbitrary plugins.
