Premium Portfolio Features for Phlox theme < 2.3.5 - Contributor+ Stored XSS

Description

The plugin is vulnerable to Stored Cross-Site Scripting via the plugin's 'aux_recent_portfolios_grid' shortcode due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
