PRIOn knowledge basePRION:CVE-2023-2833Authorization
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.
