What the vulnerability does

The EAN for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'alg_wc_ean_product_meta' shortcode in all versions up to, and including, 4.8.7 due to insufficient input sanitization and output escaping on user supplied attributes.
