This occurs due to insufficient restrictions placed on the 'rx_set_screen_options' function. Attackers can exploit this flaw by manipulating parameters during a screen option update, potentially enabling them to alter their user role. It's crucial for site administrators to update to a patched version to mitigate this vulnerability.
