What the vulnerability does
01Description
The Gift Up Gift Cards for WordPress and WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'giftup' shortcode in all versions up to, and including, 2.20.1 due to insufficient input sanitization and output escaping on user supplied attributes.
