WP Shortcodes Plugin < 7.1.6 - Contributor+ Stored XSS via su_members Shortcode

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the plugin's 'su_members' shortcode due to insufficient input sanitization and output escaping on user supplied 'color' attribute. 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.
