The UserPro plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.1.1. This is due to missing or incorrect nonce validation on the 'export_users' function. This makes it possible for unauthenticated attackers to export the users to a csv file, granted they can trick a site administrator into performing an action such as clicking on a link.

The UserPro plugin for WordPress is vulnerable to sensitive information disclosure via the 'userpro' shortcode in versions up to, and including 5.1.1. This is due to insufficient restriction on sensitive user meta values that can be called via that shortcode. This makes it possible for authenticated attackers, with subscriber-level permissions, and above to retrieve sensitive user meta that can be used to gain access to a high privileged user account.

The UserPro plugin through 4.9.23 for WordPress allows XSS via the shortcode parameter in a userpro_shortcode_template action to wp-admin/admin-ajax.php.

The UserPro plugin before 4.9.17.1 for WordPress, when used on a site with the "admin" username, allows remote attackers to bypass authentication and obtain administrative access via a "true" value for the up_auto_log parameter in the QUERY_STRING to the default URI.

Multiple cross-site request forgery (CSRF) vulnerabilities in the User Protect module 5.x before 5.x-1.4 and 6.x before 6.x-1.3, a module for Drupal, allow remote attackers to hijack the authentication of administrators for requests that (1) delete the editing protection of a user or (2) delete a certain type of administrative-bypass rule.
