## Description

The Orbit Fox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Header/Footer Scripts Customizer settings in all versions up to, and including, 3.0.12, due to the obfx_header_scripts and obfx_footer_scripts settings being gated only by the edit_theme_options capability rather than unfiltered_html, with no sanitization on save and unescaped output in wp_head and wp_footer. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
