The ProfileGrid WordPress plugin before 5.3.1 provides an AJAX endpoint for resetting a user password but does not implement proper authorization. This allows a user with low privileges, such as subscriber, to change the password of any account, including Administrator ones.
The ProfileGrid WordPress plugin before 5.1.1 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting
The ProfileGrid – User Profiles, Memberships, Groups and Communities WordPress plugin is vulnerable to Stored Cross-Site Scripting due to insufficient escaping via the pm_user_avatar and pm_cover_image parameters found in the ~/admin/class-profile-magic-admin.php file which allows attackers with authenticated user access, such as subscribers, to inject arbitrary web scripts into their profile, in versions up to and including 1.2.7.
The profilegrid-user-profiles-groups-and-communities plugin before 2.8.6 for WordPress has remote code execution via an wp-admin/admin-ajax.php request with the action=pm_template_preview&html=<?php substring followed by PHP code.
