Shortcodes and extra features for Phlox theme <= 2.15.5 - Contributor+ Stored XSS via Custom JS

Description The plugin is vulnerable to Stored Cross-Site Scripting via the custom JS parameter due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor access or higher, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
