Qode Essential Addons < 1.5.3 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Plugin Installation/Activation

Description The Qode Essential Addons plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the install_plugin() function in all versions up to, and including, 1.5.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to install and activate arbitrary plugins.
