 "title": "User Frontend <= 4.3.13 - Unauthenticated Stored Cross-Site Scripting via Category Name",
 "description": "The User Frontend plugin for WordPress is vulnerable to Stored Cross-Site Scripting via taxonomy term names in all versions up to, and including, 4.3.13 due to term names being output without escaping in the Vue-mounted admin form builder, allowing both HTML and Vue template injection. This makes it possible for unauthenticated attackers, where a frontend form lets guests submit new category terms, to inject arbitrary web scripts that execute when an administrator opens that form in the form builder.",
