The ReviewX plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.6.13 due to insufficient restriction on the rx_set_screen_options function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify their user role by supplying the wp_screen_options[option] and wp_screen_options[value] parameters during a screen option update.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
