Description
The UsersWP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the uwp_user_badge shortcode and block in all versions up to, and including, 1.2.80, due to insufficient input sanitization and output escaping on user-supplied attributes such as 'onclick', 'link', 'badge', 'hover_content' and 'hover_icon'. The 'onclick' value is written into an inline event handler, and the 'link' value is written into the badge's href without a protocol check. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
