Description

The Companion Portfolio – Responsive Portfolio Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'companion-portfolio' shortcode in all versions up to, and including, 2.4.0.1 due to insufficient input sanitization and output escaping on user supplied attributes.
