CVE-2021-24522 is a medium-severity vulnerability rated 6.1/10 on the CVSS scale. The User Registration, User Profile, Login & Membership – ProfilePress (Formerly WP User Avatar) WordPress plugin before 3.1.11's widget for tabbed login/register was not properly escaped and could be used in an XSS attack which could lead to wp-admin access. Further, the plugin in several places assigned $_POST as $_GET which meant that in some cases this could be replicated with just $_GET parameters and no need for $_POST values.. EPSS estimates a 1.29% chance of exploitation in the next 30 days.
