The Kredeum NFTs, the easiest way to sell your NFTs directly on your WordPress site plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'kredeum_opensky' shortcode in all versions up to, and including, 1.6.9 due to insufficient input sanitization and output escaping on user supplied attributes.
