Shortcodes and extra features for Phlox theme <= 2.15.7 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'aux_gmaps' Shortcode

Vulnerability Description

The Shortcodes and extra features for Phlox theme plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'aux_gmaps' shortcode in all versions up to, and including, 2.15.7 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.
