The UsersWP plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to and including 1.2.60. This is due to insufficient input sanitization of user-supplied URL fields and improper output escaping when rendering user profile data in badge widgets. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts that will execute whenever a user accesses a page containing the affected badge widget.
