The Betheme theme for WordPress is vulnerable to Stored Cross-Site Scripting via the theme's 'icon_box_2' shortcode in all versions up to, and including, 28.4 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
