Summary
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.
Risk Assessment
An attacker can inject malicious scripts that execute in visitors' browsers, potentially leading to session theft, account takeover, or malware distribution.
Recommendation
Update the Betheme theme to a version newer than 28.4. Additionally, restrict user privileges and apply security practices for shortcodes.
